Lawn Mower Carburetor: When and How to Clean
Few pieces of home maintenance equipment work as hard as your lawnmower. Despite its rough-and-tumble life, though, many lawnmowers don’t get the care and attention they need.
This is especially true when it comes to the lawnmower’s carburetor. Your lawnmower’s carburetor is a critical component for functionality and will be the thing that determines whether your lawnmower works for years or conks out early.
With that in mind, learning to clean your lawn mower carburetor is a critical part of preventative maintenance. Here’s what you need to know.
When Should you Inspect and Clean a Lawnmower Carb?
While the exact recommendations for this vary from household to household, most experts say you should check and clean a lawnmower carb at least a few times a year.
The reason for this is simple: as you use your lawnmower, the grass, twigs, and debris the blade kicks up make their way into the small engine. Some of that debris eventually wind up inside of the carburetor – clogging fuel and air passages and reducing the performance of the mower’s engine.
Steps to Clean a Carburetor
Here are four steps to follow to clean your carb quickly and easily:
Start by Checking Your Air Filter
The first step in cleaning the carburetor is to check the air filter to ensure it’s free of debris. A clogged air filter will create black smoke that spills from the exhaust. It will also make it difficult for your carb to get the air it needs to “breathe.”
Check all Connections
Next, it’s time to check the connections that run from a carburetor’s throttle and choke plates, since these things can stick when they get dirty.
Additionally, constant vibration and wear can loosen screws over time, contributing to strange handling and additional carb issues.
Use Carburetor Cleaner
Next, it’s time to pick up a carburetor cleaner to get rid of the deposits within the carb, which can clog both air and fuel passages and interrupt the performance.
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleaner, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.
After you’ve coated the surfaces of the carb with this cleaner, give the lawnmower a once-over for other maintenance issues, like stale fuel, bad air filters, old spark plugs, dirty engine oil, and more.
Now it’s time to check the settings on your carburetor to see if anything should be adjusted or updated.
If you’re not sure what you’re looking for, take your carburetor to a local repair service, which can help you identify issues and ensure you’re running your carb as efficiently as possible. This professional will also be able to help you understand why you shouldn’t drain the fuel and how best to care for your lawnmower in the future.
Keeping Your Carburetor Clean and Healthy
A critical piece of your engine’s functionality, the carburetor keeps your lawnmower running strong and functioning well. When you understand how to clean your lawnmower carburetor, you can keep your lawnmower in great shape for years to come, no matter how hard you use it.
Lawnmower Won’t Start? Do this.
Bad gas or a dirty carburetor are the most common reasons for a lawnmower that starts hard or runs rough.

A lawnmower that won’t start, especially when taken from storage, is almost always due to one problem: bad gas.
Storing a lawnmower in the fall without adding gasoline stabilizer to the fuel tank can cause the fuel to break down and plug the fuel passages. If fixing that problem doesn’t help, there are a few others that can help fix a lawnmower that won’t start, as we explain here.
How to Fix a Lawnmower That Won’t Start
Replace the Bad Gas
Over time (like the six months your lawnmower sat in your garage over the winter), the lighter hydrocarbons in gas can evaporate. This process creates gums and varnish that dirty the carburetor, plug fuel passages and prevent gas from flowing into the combustion chamber.
The carburetor bowl below formed corrosion and deposits during storage, which can easily plug fuel passages and prevent the engine from starting.
Storing equipment without stabilizing the gas can lead to deposits that foul the carburetor or injectors.
Ethanol-containing gas can absorb water from the atmosphere, which can lead to phase separation, which occurs when ethanol and gas separate, much like oil and water. Ethanol that has absorbed enough moisture and has sat long enough can foul the fuel system and prevent the engine from starting.
No matter how many times you yank the pull cord and pollute the air with your advanced vocabulary, the lawnmower won’t start if it’s trying to run on bad gas.
In extreme cases, evaporation of lighter hydrocarbons can change the gasoline’s composition enough to prevent it from igniting. The gas may be fueling the engine, but it doesn’t matter if it won’t ignite.
Bad Gas in Your Lawnmower? Here’s How to Fix It
If you neglected to add gasoline stabilizer to the fuel prior to storage, empty the tank and replace with fresh gas. If the tank is nearly empty, simply topping off with fresh gas is often enough to get it started.
On some mowers, you can easily remove and empty the fuel tank. Sometimes that’s more trouble than it’s worth. In these cases, use a fluid extraction pump or even a turkey baster to remove the bad gas. You don’t need to remove all of it; but try to get as much out as possible.
Clean the Carburetor
You’ve replaced the fuel, but your lawnmower still won’t start.
Next, try cleaning the carburetor. Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish and gums.
Remove the air filter and spray carburetor cleaner into the intake. Let it sit a few minutes to loosen deposits.
On some carburetors, you can easily remove the float bowl. If equipped, first remove the small drain plug and drain the gas from the bowl. Remove the float bowl cover and spray the float and narrow fuel passages with carburetor cleaner.
This kind of “quick-and-dirty” carburetor cleaning is usually all it takes to get the gas flowing again and your lawnmower back to cutting grass.
If not, consider removing the carburetor from the engine, disassembling it and giving it a good cleaning. Be forewarned, however: taking apart a carburetor can lead to nothing but frustration for the uninitiated. Take pictures with your phone to aid in reassembly. Note the positions of any linkages or the settings of any mixture screws, if equipped. If you’re at all reluctant, visit the servicing dealer instead.
Consider replacing the carburetor altogether. It’s a fairly simple process on most smaller mowers and it’s often less expensive than taking it to the dealer.
Direct compressed air from the inside of the air filter out to remove debris that may be reducing airflow and preventing the lawnmower from starting.
Clean/Replace the Air Filter
With the air filter removed, now’s the perfect time to clean it.
Tap rigid filters on a workbench or the palm of your hand to dislodge grass clippings, leaves and other debris. Direct compressed air from the inside of the filter out to avoid lodging debris deeper into the media.
Use soap and water to wash foam filters. If it’s been a few years, simply replace the filter; they’re inexpensive and mark the only line of defense against wear-causing debris entering your engine and wearing the cylinder and piston rings.
An incorrectly gapped spark plug can prevent the engine from starting. Set the gap to the specification given in the owner’s manual.
Check the Spark Plug
A dirty or bad spark plug may also be to blame. Remove the plug and inspect condition. A spark plug in a properly running four-stroke engine should last for years and never appear oily or burned. If so, replace it.
Use a spark-plug tester to check for spark. If you don’t have one, clip the spark-plug boot onto the plug, hold the plug against the metal cylinder head and slowly pull the starter cord. You should see a strong, blue spark. It helps to test the plug in a darkened garage. Replace the plug if you don’t see a spark or it appears weak.
While you’re at it, check the spark-plug gap and set it to the factory specifications noted in the lawnmower owner’s manual.
If you know the plug is good, but you still don’t have spark, the coil likely has failed and requires replacement.
Did You Hit a Rock or Other Obstacle?
We’ve all killed a lawnmower engine after hitting a rock or big tree root.
If your lawnmower won’t start in this scenario, you probably sheared the flywheel key. It’s a tiny piece of metal that aligns the flywheel correctly to set the proper engine timing. Hitting an immovable obstacle can immediately stop the mower blade (and crankshaft) while the flywheel keeps spinning, shearing the key.
In this case, the engine timing is off and the mower won’t start until you pull the flywheel and replace the key. It’s an easy enough job IF you have a set of gear pullers lying around the garage. If not, rent a set from a parts store (or buy one…there’s never a bad reason to buy a new tool) or visit the dealer.
My Lawnmower Starts But Runs Poorly
If you finally get the lawnmower started, but it runs like a three-legged dog, try cleaning the carburetor with AMSOIL Power Foam. It’s a potent cleaning agent designed to remove performance-robbing carbon, varnish and other gunk from carburetors and engines.
Add Gasoline Stabilizer to Avoid Most of These Problems
Which sounds better? Completing all these steps each year when your lawnmower won’t start? Or pouring a little gasoline stabilizer into your fuel tank?
Simply using a good gasoline stabilizer can help avoid most of the problems with a lawnmower that won’t start.
AMSOIL Gasoline Stabilizer, for example, keeps fuel fresh up to 12 months. It helps prevent the lighter hydrocarbons from evaporating to reduce gum and varnish and keep the fuel flowing. It also contains corrosion inhibitors for additional protection.
I have a five-gallon gas can in my garage from which I fuel two lawnmowers, two chainsaws, two snowblowers, a string trimmer, an ATV and the occasional brush fire. I treat the fuel with Gasoline Stabilizer every time I fill it so I never have to worry about the gas going bad and causing problems.
You can also use AMSOIL Quickshot. It’s designed primarily to clean carburetors and combustion chambers while addressing problems with ethanol. But it also provides short-term gasoline stabilization of up to six months.
Use a Good Motor Oil for Your Lawnmower
Although motor oil has no bearing on whether your lawnmower starts or not (unless you don’t use oil at all and seize the engine), it pays to use a high-quality motor oil in your lawnmower.
This is especially true for professionals or homeowners running expensive zero-turn or riding mowers.
Lawnmower engines are tougher on oil than most people realize. They’re usually air-cooled, which means they run hotter than liquid-cooled automotive engines.
They often run for hours in hot, dirty, wet conditions. Many don’t have an oil filter, further stressing the oil.
In these conditions, motor oils formulated for standard service can break down, leading to harmful deposits and reduced wear protection.
For maximum performance and life, use a motor oil in your lawnmower designed to deliver commercial-grade protection, like AMSOIL Synthetic Small-Engine Oil.
Its long-life formulation has repeatedly demonstrated its ability to safely exceed original equipment manufacturer (OEM) drain intervals in the toughest conditions. It provides an extra measure of protection when equipment goes longer between oil changes than is recommended by the OEM.
Where is the Carburetor on a Lawn Mower? (every mower)
Do you need to do some troubleshooting or maintenance with your lawn mower? If so, you’ve probably wondered where the carburetor is on a lawn mower. The location of this component of your mower’s engine can vary depending on the type of lawnmower you have.
In today’s article, I’ll tell you what a lawn mower carburetor looks like, where it usually is found on every type of mower, and provide a list of cleaning tips to maintain your mower’s carb.
All About the Lawn Mower Carburetor
What it Looks Like, What Parts of the Mower it Connects to, and
The carburetor is an essential part of your lawn mower’s engine. It makes sure that the correct combination of fuel and air will go into the engine cylinder. This is essential for combustion to occur.
When the spark plug ignites the fuel and air mixture, it combusts and pushes the engine piston in a downward direction. This, in turn, rotates the crankshaft. This makes the lawn mower blade spin.
Depending on the type of lawn mower you have, the wheels of your mower (for example, a riding mower or self-propelled mower) will also start to rotate.
How to Find and Identify Your Mower’s Carburetor
The carburetor is part of the mower’s engine. Typically, it is bolted to the side or top of the engine. It is also connected to the gas tank, and will typically be located just below or behind your air filter. Most lawn mower manufacturers make the air filter housing easily accessible and easy to identify so that owners can change out the filter as part of their annual maintenance. Find the air filter and your mower’s carburetor will be the next part of your mower’s engine, right behind it.
While the location will vary by manufacturer, there are a few qualities most carbs share to make them easier to identify.
Carburetors are metal and rectangular in shape. Your mower’s carb will often have black areas, such as a black circle and trim on the right and left.
In this article I’ll walk you step-by-step through locating and servicing your mower’s carburetor, with specific tips for locating the carburetor on every type of lawn mower.
Different Kinds of Lawnmower
In this section, we will go over the different kinds of lawnmower and where you can usually find the carburetor in each. The two main kinds of lawnmower are walk-behind and riding.
There are four main types of walk-behind mowers, which I list below – if you own a walk-behind mower make sure you know which type it is so that you can refer to the correct part of this article to locate your mower’s carburetor:
- Electric walk mower: An electric walk mower is appropriate for smaller properties.
- Self-propelled mower: A self-propelled mower is handy because it propels itself, meaning it’s a lot less work when mowing hilly areas. If you get a self-propelled mower, you can choose front-wheel drive or rear-wheel drive. Front-wheel drive is suitable for level ground. A self-propelled mower with rear-wheel drive is most suitable for sidehill and uphill mowing.
- Two-function mower: A two-function mower mulches and bags as well as does the usual grass cutting.
- Three-function mower: A three-function mower cuts the grass as well as bags, mulches, and side discharges.
There are three main types of riding lawn mowers, which I list below. If you own a riding mower, make sure you know which type it is so that you can refer to the correct part of this article to locate your riding mower’s carburetor:
- Rear Engine Riding Mower: The rear engine riding mower is the smallest of riding mowers.
- Lawn Tractor: Lawn tractors (sometimes called garden tractors) have very powerful engines, which are great for large properties.
- Zero Turn Radius Mower: Zero turn radius mowers are also very powerful, but they are easier to maneuver.
Carburetor Location in Walk-Behind Mowers
For walk-behind mowers, you will find the carburetor at the side of the mower, in the area above the base of the mower. As we mention later, the carburetor is connected to the air intake and air filter of the mower. Therefore, finding these components makes it easy to find the carburetor.
If you’re having trouble finding them, search for square-shaped or round-shaped filter housing. This will generally be on the side of the mower’s engine, though it’s sometimes on the top.
The air filter case is usually plastic and pops open easily to provide easy access to the filter for maintenance. The mower’s carburetor is just behind the air filter’s housing, and there are typically 2-3 bolts that can be loosened to remove the filter housing and reveal the carb.
This video does a nice job demonstrating the removal and cleaning of the carburetor on a walk-behind mower:
The exact process for repairing or replacing a carburetor in a riding mower will depend on your exact model, and it tends to be more complicated than working with the carburetor of a walk-behind mower, so you may choose to hire a professional at a small engine repair shop to do this for you.
If you are going to do a carb repair or replacement yourself, my advice is to consult the manual that came with your machine, and document every step of the process so that you can remember how the carb was set up and have an easier time re-attaching everything properly.
Here’s a video from Sears that walks you through replacing the carburetor on a Craftsman Mower. It provides a good sense of what’s involved in this project, what your riding mower’s carburetor looks like, and where the carb is located on some riding mowers:
How to clean lawn mower carburetor in under 5 minutes!
- Step 1: Turn off your mower’s ignition and use the parking brake. To stop any accidental rolling, put the mower in gear.
- Step 2: Make the mower’s engine accessible by releasing any restraining devices (such as hood latches) that are holding down the hood.
- Step 3: Find the air intake and the filter. You should find filter housing (square or round-shaped) on the side or top of the engine. This will have slits or holes in the top. The filter housing will be attached to the carburetor by screws or latches. This housing contains a filter made of foam or paper. The filter found within the housing is there to stop dust and dirt from getting into your mower’s carburetor.
- Step 4: Locate the fuel line that comes from the gas tank. You can use this information to find where the gas tank. Gas tanks will usually be mounted in a place that makes it easy to access for re-fueling and is often black.
- Step 5: Find the fuel line that comes from the tank. This line will usually be situated in close proximity to the bottom of the tank. A small clamp is usually there to attach it. You can trace the fuel line that attaches the tank to where it connects with the carburetor.
Why is it Important to Clean Your Lawn Mower’s Carburetor?
The carburetor of your lawn mower needs to be kept clean in order for the machine to work as it should.
Think of the carburetor in a car. If it isn’t kept clean and properly maintained, your vehicle will not run properly.
This is the same with a small engine such the kind you have in a lawn mower.
If you are having certain problems with your mower, there is a good chance that you need to clean the carburetor. Below are some signs of a dirty carburetor:
- You’re having problems with the engine stalling when you are trying to cut the lawn.
- You are having difficulty starting the mower.
- There is black smoke coming from the muffler.
- The engine is sputtering or running turbulently during mowing.
- You have noticed an increase in your mower’s fuel consumption, even though you are using the way you always have.
How to Clean a Mower Carburetor Once You Locate It
Let’s take a look at how to clean a lawn mower carburetor.
Please note that these are general instructions and you should consult with the instructions that come with your particular mower before you proceed.
Removing the Carburetor
- You must completely remove the carburetor from the lawn mower before trying to clean it.
- If it is necessary, take off the engine cover.
- Take off the cover of the air filter, the filter, and the housing of the air filter.
- If possible, turn off the fuel valve. If this isn’t applicable, make a crimp in the fuel line. After that, take it off the carburetor. Be ready for a bit of fuel to spill out. You can use a rag to deal with the mess.
- Get the choke and throttle linkages detached from the carburetor throttle lever.
- Use a sliding motion to remove the carburetor from the mounting bolts.
- If necessary, release the carburetor bowl by unthreading the screw. This will release the bowl.
- Release the float and needle by removing the float pin.
Cleaning the Carburetor
- To completely take apart the carburetor, you will possibly have to unthread screws so that the primer bulb and base are released. After that, take out the metering plate, diaphragms, and gaskets.
- The outlet ports and carburetor intake should be exposed. You should then use a special carburetor cleaner spray (if you don’t have that, then WD-40) to clean out residue from the ports.
- If there is a bowl, clean it out.
- Check if there are any signs of rust in the carburetor. If so, get rid of it with sandpaper.
- Give the carburetor time to dry. After that, put it back together. Ensure that the diaphragms, metering plate, gaskets, and primer base are correctly positioned. Also do the same with the float and float needle.
- Ensure that you put the bowl gasket back in its correct place. Reinstall it if that is necessary.
- Use a sliding motion to reinstall the carburetor onto the mounting bolts. Get the throttle linkages re-attached to the throttle lever.
- Reattach the carburetor to fuel line.
- Reinstall the air filter, filter cover, and air filter housing.
- If this is necessary, reinstall the engine cover.
What if the Carburetor Needs Repairs?
It is possible that your carburetor will need repair as well as cleaning. If that is the case, you can consider buying a carburetor repair kit. This will help you with replacing some of the major components of the carburetor, such as the diaphragms, gaskets, float, and float needles. You can probably find a kit that matches your mower on Amazon for less than 20.
If you find that the carburetor continues to have poor performance, it’s possible that you will have to get a new carburetor and replace the old one. The price of a replacement carburetor will typically be about 50, and you can find genuine manufacturer’s carb replacements on Amazon (like this one for a Honda self-propelled mower).
If you’re sure your lawn mower issues are the result of carburetor problems, it’s generally easier to buy a new carb and replacing the whole thing vs attempting to repair a few gaskets or parts.
In my experience a repair kit works better in theory than in practice, and your average weekend warrior is better off replacing the whole thing if determined to DIY a fix. For 30 more, why not install a brand new carb?
The other option (recommended for most people) is to take your mower to a small engine repair shop and let them do the work for you. This is less expensive than you’d think, and will save you some time and headaches.
For optimal lawn mower maintenance, you should clean the carburetor every year.
This will help your mower always perform at the optimal level and help to hold off problems that will require parts replacement or full replacement of the carburetor.
And you don’t have to take your carb out to keep it running like new – I give my mower a shot of Gumout Carb and Choke Cleaner (Amazon link) before every mow to keep it running like new. It’s like 5 a can and lasts a whole season.
Maintain Your Lawn Mower So It Lasts!
Understanding how your lawn mower works and how to maintain it is key to making it last.
Purchasing a new lawn mower is an investment, so it’s well worth taking the time to read the manual and understand all the components and their functions.
Where is the carburetor on a lawn mower?
Learn where is the carburetor on a lawn mower so you can maintain the performance of your mowing machine.
Time for some mower maintenance? If your machine hasn’t been running reliably, you might need to figure out where is the carburetor on a lawn mower to see if it needs cleaning. A dirty carburetor can cause a variety of problems – like issues starting the mower or the engine stalling when in use. So, if cutting the grass has become even more of a chore thanks to a faulty lawn mower, checking the carburetor is a good place to start.
Learning how to maintain and repair your garden equipment is a great way to save money, as you won’t have to buy replacements as often. The best lawn mowers can last many years with regular maintenance, which also helps reduce the number of machines that go to waste when they could be repaired. Whether you use the best riding lawn mowers or a walk-behind mower to look after your lawn, this guide explains how to find, clean, and safely maintain the carburetor so your machine always runs like a dream.
Where is the carburetor on a lawn mower?
The carburetor is an essential component of a gas-powered lawn mower engine. In simple terms, it ensures that the correct balance of fuel and air enters the engine cylinder, where it will be ignited by the spark plug, combust, and make the engine work.
On a push or walk-behind mower, the carburetor is usually located on the side or top of the engine, just behind the air filter and above the base of the mower. You’re looking for a silver and black component, made mostly of metal. It’s likely it will be hidden by the air filter, which the carburetor is connected to. To find the air filter, look for a square or round plastic filter cover. This opens to allow access to the air filter, which sits in a plastic housing. You’ll need to remove the filter, then unbolt the housing to reveal the carburetor.
On a riding mower, the carburetor is generally found on the side or top of the engine. Like on a push mower, it will typically be behind the air filter, so you’ll have to remove the air filter and filter housing to access the carburetor, which is connected by a fuel line to the gas tank.
If in doubt, one of the best ways to find where is the carburetor on a lawn mower is to check the owner’s manual, as the location of the carburetor can vary depending on the model or manufacturer.
What is the importance of a carburetor on a lawn mower?
The carburetor is an essential component of any lawn mower engine, as Tom Monson, CEO of Monson Lawn Landscaping, explains: “The carburetor on a lawn mower mixes air and fuel in the proper ratio for the engine to run efficiently and effectively.” As you mow your lawn, the carburetor adjusts the combination of fuel and air depending on how long the engine has been running, your speed, and the type of terrain. This ensures that you get the best performance out of your mower.
A clean carburetor that’s in good condition will keep your lawn mower running reliably and efficiently, which is why carburetor maintenance is an essential part of taking care of your mower. The most important thing is to keep the carburetor clean, because even if the engine is running, a dirty carburetor can still cause problems.
Signs of an issue with the carburetor
Because the carburetor on a lawn mower is usually hidden behind the air filter, you might not notice if it’s dirty. However, if you experience any of the following when cutting your grass, it could be a sign that the carburetor needs a clean;
Problems starting the engine. You may have to pull the starter rope multiple times to get the engine running on your push mower, or turn the ignition more than once on your riding mower.
Engine stalling. Once the mower is running, you might find that the engine stalls, either immediately after starting or while you are mowing the lawn.
Spluttering and shaking. A dirty carburetor might cause the engine to sputter or shake while it’s running, making it more difficult to maneuver the machine.
Increased fuel consumption. Despite mowing the lawn as you usually do, you might notice that your mower is using more fuel. This is a common sign that the engine isn’t running as efficiently, which could indicate an issue with the carburetor.
How to clean and maintain the carburetor
To get the best out of your lawn mower, you should clean the carburetor once a year. Once you’ve figured out where is the carburetor on a lawn mower like the one you have, you can remove the carburetor ready for cleaning. Follow these steps to do it yourself at home, keeping the owner’s manual for your mower nearby for reference;
Clean the machine
Clean the outside of the engine first to remove any dirt that could contaminate your newly-cleaned carburetor. Make sure you have a clear, clean work area where you won’t lose any small parts.
Remove the air filter
Open or remove the air filter cover, then remove the air filter and the filter housing.
Turn off the fuel valve
Where possible, turn off the fuel valve. Alternatively, crimp the fuel line using a clamp or crimping tool to prevent fuel leaking while you work. Some fuel will still spill out, so keep a cloth or rag handy.
Unfasten the carburetor
Remove the carburetor by unfastening the bolts that hold it to the engine and disconnecting the throttle and choke linkage cables.
Pay attention to the details
Make a note of where cables and bolts are positioned so you can replace them later. Keep any fasteners or small parts safe.
Remove the careburetor
Remove the carburetor from the mounting studs, noting its position so you don’t reinstall it the wrong way up.
Start to disassemble
Carefully disassemble the carburetor, using a carburetor cleaner spray or WD-40 to clean as you go. Ryan Farley, CEO of LawnStarter, recommends using a cleaner designed for small engines. “These are formulated to remove dirt, debris, and built-up varnish and gum deposits from the carburetor without damaging any delicate parts”.
Get rid of rust
Remove any signs of rust using sandpaper.
Allow it to air dry
Allow the carburetor to dry, before putting it back together.
Reattach the carburetor
Replace the carburetor on the mounting studs, reconnect the linkage cables, and reinstall the air filter, cover, and housing.
Safety tips for maintaining the carburetor
Keep these tips in mind to safely maintain the carburetor on your lawn mower;
Although it’s possible to remove and clean a carburetor yourself, it’s a dirty, fiddly job that you might want to leave to the professionals. Your local small engine repair shop should be able to help.
If you do decide to clean your own carburetor, always wear gloves and cover your work area to protect it from damage or debris, including fuel spillages.
After cleaning your carburetor, you might find that your mower still doesn’t work reliably, which may mean that the carburetor or another part needs replacing. Again, it’s possible to fit a new carburetor yourself, but you may want to get some advice from a repair shop first.
If you’re up for trying a DIY lawn mower repair, replacing the entire carburetor is usually simpler and more cost-effective than replacing individual gaskets or small parts.
