Introduction to Carburetors

A lawn mower is an essential tool for maintaining a beautiful lawn. Like any piece of lawn equipment, it must be properly maintained to ensure it does not fail while in use.

Battery-powered mowers are gaining popularity, but the majority of lawn mowers still run on gas engines which means they have a carburetor.

Gas engine mower’s runs by gas mixing with air and being ignited by a spark like other combustion engines. Air passes through an air filter in the carburetor and mixing with the fuel before the spark plug ignites the gas/air mix.

The purpose of a lawn mower air filter is to prevent dust and dirt from clogging up in the carburetor and engine. Most fuel lines also have a filter, in this case, a fuel filter, to keep any debris in the gas from entering and damaging the engine’s internal parts. Even if the debris in your engine doesn’t immediately cause noticeable problems, the result is energy loss and increased gas consumption.

The carburetor is one of the most essential components of a lawn mower. The carburetor ensures the proper mix-up of gasoline and air in the engine to keep the engine running properly.

The Importance of Keeping Your Mower’s Carburetor Clean

Cleaning your carburetor ensures it will continue to work properly. If not, its ability to regulate combustion will be seriously compromised. Air should flow into the carburetor, mix with the gas, and start the engine.

Everyone knows lawn mowers cut grass. When the blades are actively engaged, the engine is put under more stress and this is when it is even more imperative that your lawn mower carburetor is clean. Over the years we have run into situations where the engine operates as expected until put under the additional stress of having the blades engaged.

Therefore, regular maintenance of the engine is necessary. First, check if your mower is working properly and clean it. As there are different models of engines, when disassembling, you should look carefully or always refer to the assembly manual and take pictures as you go.

Make sure the fuel line is shut off before removing the carburetor. Most have a knob you can turn to shut off the flow of fuel through the line to the carburetor. If yours does not, you can pinch the line to temporarily cease the flow of fuel.

After removing the carburetor, clean it thoroughly so that its floating valve can move freely. Then replace the carburetor and open the fuel line back up.

Items Needed to Clean a Carburetor

You will need a handful of items you can find at any auto parts store to clean the carburetor on your lawn mower.

Carburetor Cleaning Material List:

  • Carb Cleaner

Steps for Cleaning the lawnmower carburetor

Cleaning a lawn mower carburetor is something anyone that is slightly mechanically inclined can do on their own. It is important to pay attention as you disassemble the carburetor so you know how to reassemble it! Once again, we recommend you take many pictures to document the disassembly to assist with reassembly.

Here are the steps to clean your air filter carburetor:

The first step to cleaning carburetor is to remove it from the engine. Once you have done this, disassemble, clean it, and maintain it. Make sure you have shut off the flow of fuel prior to removing the carburetor.

  • Prepare to Remove the Carburetor From Your Lawn Mower: Remove the spark plug by pulling on the spark plug wire to disconnect. Shut off the flow of fuel to the carburetor by turning the shut-off valve or pinching the line. Then identify the bolts or screws attaching your carburetor to your mower’s engine and remove them. Sometimes you will need to remove or loosen additional engine components to fully remove the carburetor.
  • Remove the cap screws holding the carburetor from the engine and be very careful not to damage the diaphragm between them.
  • Carefully remove the rubber gasket from your carburetor. If you don’t see it, it may be stuck to the engine. You don’t want carb cleaner touching your gasket as it can corrode it. If your gasket is damaged at all, it must be replaced with a new gasket before reinstalling or fuel will leak.
  • Remove the bowl, metal bulb from the bottom of the carburetor using your tools. Clean it with an aerosol cleaner and a clean shop towel.
  • Remove the 0 ring that sticks to the bottom of the bowl. Check for cracks or wear, replace, and set aside.
  • Get a carb cleaner, or carburetor cleaner, then inject the fluid into each port and make sure it comes out at the other end of the port. These ports are very narrow and easily clog. That is why the air filter and fuel filter are so important!
  • If you are not noticing the carb cleaner successfully traveling through the ports, try using compressed air with a needle tip air gun to blast out any blockage. If that doesn’t work, try soaking the carburetor in carb cleaner and trying again hours or days later if needed.
  • Reassemble any internal parts of the carburetor you may have removed in the process. Once complete you can start reattaching the carburetor to your engine.
  • It is recommended to put a small amount of oil on the gasket before sealing it back to the engine when tightening the bolts that connect it.
  • Turn your fuel line back on.

Pro Tips For Cleaning Carburetors

You’ve just learned about the importance of the air filter and fuel filter. They are probably the reason you needed to clean your carburetor in the first place! Why not replace these inexpensive items while you are working on your carburetor?

Do not use wire brushes or thin pieces of wire to clean a carburetor. Carburetors are calibrated to achieve the perfect air to fuel mix and must be 100% sealed. Using any type of hard material to clean a carburetor is a great way to compromise your carburetor.

Additional Lawn Mower Maintenance Tips

  • Use only fresh fuel for your lawn mower. Old or stale gasoline will thicken and reduce flow to the carburetor. This is actually one of the problems that keep your mower from starting.
  • Check the oil level regularly and change the oil at least once a year or per your mower manufacturer’s recommendations. Dirty oil is another great way to ruin an engine quickly.
  • Make sure your lawnmower blades are kept sharp as dull blades will tear your grass instead of cutting it. Learn more about sharpening mower blades.
  • Check the mower’s spark plug at least once a year. If it is dirty, you can clean it or replace it.
  • Make sure your lawnmower wheels are inflated, rotating freely, and haven’t been damaged.
  • After each use, clean the bottom of the mower to remove accumulated grass. If grass collects under your mower’s deck, you will notice a dramatic drop in ‘cut quality.’ The space above your mower’s blades under the deck most remain open for the blades to create lift and provide a flush cut of the turf.
  • Check wires, wire connections, belts, and lines on your mower to ensure they are fully connected, not pinched, and have not been cut or melted.
  • Always prepare your lawnmower correctly for winter, even if it will only be out of use for a month. To do this, siphon the fuel out of the gas tank and run the engine until it completely drains the carburetor of fuel.

By ensuring that your lawnmower is in good condition, you will be rewarded with several years of exceptional use. Follow the maintenance tips above on a regular basis to ensure that the mower always starts on the first start and mows the lawn as you would expect.


Proper care of your lawn mower parts will keep them in top shape, and most importantly, reliable and safe. There is nothing more frustrating than going to mow the lawn to realize your lawn mower will not start. If this happens you to, we hope this article helps and remember, there is a good chance it has something to do with your carburetor.

1.Safety First

They say that ‘safety is better than first aid.’ As such, it’s very important that every time you carry out repair or maintenance work of any kind, let safety be a key concern. For instance, when taking apart a carburetor, the old oil can be highly toxic, ensure you’re working in a well-ventilated area. In case you’re in your home garage, ensure that all the Windows and doors are open. You can also use a garage fan, if you have one. If your shed does not have any ventilation areas, consider working elsewhere.

Remove the Outer Casing and Air Filter

The procedure on this depends on the type of your lawn mower. Ideally, it involves un-tightening of a few screws and removal of the covering panel to reveal the mower’s innards. Once your remove the air filters, you’ll see the carburetor. Check your Air Filters to ensure they’re clean and free of debris. Dirty air filters can create black smoke that spills from the exhaust thus making it hard for the carburetor to get the air it needs to function properly.

Removing the Carburetor

The carburetor is normally firmly bolted in place but it comes off easily. Using a nut driver, unbolt it and then drain the fuel line while holding it to the engine.Detach the throttle cables and be ready with a rag or any piece of cloth to wipe any spillage of fuel on the carburetor and the fuel line.

Detach the carburetor from the engine and inspect all connections that run to and from the carburetor’s choke plates and throttle. If you find out that the carburetor is corroded, it’s toast, replace it with a new one. If not, proceed as below

Unbolt the carburetor’s bowl and clean the nut

Use a carburetor cleaner to clean around it.Unscrew the nut to remove the bowl. This nut is usually a jetted hole. Poke a paper clip inside to ensure that the hole is free of any dirt.

Presence of simple debris inside this hole will readily make the carburetor stop working properly; cleaning it may fix the problem.

Replace the needle

After removing the bowl, you’ll see a pin attaching the float attached to the carburetor. Remove it and replace the needle-normally found in a small gasket inside the carburetor.

Consider replacing it and be keen to fit it the right way to avoid future malfunctions.

Use a carburetor cleaner to get rid of dirt deposits within the carburetor

Dirt within the carburetor can block both fuel and air passages thus interrupting its performance.

The commercial lawnmower carburetor cleaner comes in a spray can that can easily clean the inside and outside parts of the carburetor.

Having removed all parts of the carburetor, clean them by applying a spray of the carburetor cleaner.Using a paperclip, remove any dirt inside the holes of the carburetor. Ensure they are clear of any debris.

Replace the gasket

After taking apart the carburetor, we advise that you replace the main gasket.

This is normally found between the bowl and the carburetor itself. What’s more, these gaskets are inexpensive. Simply get a new one and fit it in its place.

Check its settings

After the cleanup, check the carburetor’s settings and find out if there’s anything that should be updated or adjusted.

For those mower users who don’t buy this idea, here’s the truth: carb cleaning is incomplete without this step, why? Simply because while you were busy cleaning, you could have opened up some wires that are very essential for your carburetor’s engine to function. It beats logic, right?

To do this, use a flashlight to inspect if everything is fixed rightly. After ascertaining that all this is done, start the engine. Ideally, it should have a smoother start and shouldn’t produce any shaking sound after cleaning the carburetor.

How To Use Carburetor Cleaner On A Lawnmower

Owning a lawn mower means maintenance, as it can make all the difference when it comes to your lawn care. It’s a household essential for many, but it also requires its own attention to ensure everything keeps up and running. One of the trickiest sticking points for new mower owners is carburetor cleaner. Chorbie is here to provide a complete, step-by-step guide on how to use carburetor cleaner on a lawnmower to make certain you stay up and running. Read how you’re able to promote safety and quality in your equipment while keeping a tidy lawn.

Getting Started

The first step in any maintenance project on your mower is to understand what exactly you are cleaning and protecting. Using your lawnmower regularly will lead to sludge and debris to build up around your carburetor overtime. The grime that accumulates can greatly affect the mower’s ability to keep the engine running. In fact, without the ability to mix fuel and oxygen in the combustion engine, it will completely stop working. Allowing the problem of buildup to go unmanaged can lead to many more issues besides. In short, however, if you fail to maintain your carburetor, you will be buying an expensive new mower quite soon.

Simple Steps For Lawn Mower Carburetor Cleaning

Carburetor cleaner remedies the issue of problem buildup around your carburetor, affecting smoothness while running the engine. You’ll also increase the lifespan of your mower by using carburetor cleaner regularly and following these steps:

  • Grab a screwdriver and your preferred cleaner
  • Start by turning the mower off and letting the engine cool completely
  • Remove the air filter on the same side that you find the carburetor

Now that you’ve removed the filter and allowed the engine to cool, you can turn to reveal the grime and buildup in the carburetor.

  • Take off the carburetor cover and linkage to expose the inside
  • Wait for the inside to dry out, and then start the engine
  • Spray into the center of the carburetor as it is running.

Cleaning the carburetor while it’s running is best because it allows the cleaner to penetrate and clean the throat of the carburetor, removing deposits in the lower sections. Now for the last few steps:

  • Shut off the engine and continue spraying to get extra buildup removed
  • Replace the cover, linkage, air filter, and screw everything back in place.

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.

Where is the Carburetor on a Lawn Mower?

The carburettor on a lawn mower is located between the fuel tank and the engine.

It is usually found on the side of the engine or near its base, depending on the type of mower you have.

The carburettor mixes air and fuel before it enters the cylinder to be combusted. Generally, if you look at your lawnmower from behind, you can spot a tube running from either side of your fuel tank that connects to two chambers – this is likely where your carburettor will be located.

The carburettor on a lawn mower is usually located underneath the engine cover. It’s responsible for mixing air and fuel, which helps control the speed of your machine.

If your lawn mower isn’t running as smoothly as it should, you might need to take a look at the carburettor and see if it needs cleaning or adjusting. Remember to always exercise caution when working with any type of machinery!

What Is A Lawn Mower Carburetor?

The carburetor is a necessary component of a gas lawn mower’s engine. Its function is to regulate the proper combination of fuel from the tank and air from the environment. However, the carburetor in a lawn mower is typically positioned horizontally, unlike the carburetor system found in a vehicle.

The carburetor of a lawn mower lacks throttle butterflies and is a complex device with air, fuel, and exhaust connections.

What Does A Carburetor Do In A Lawn Mower?

Gasoline-powered engines require a correct ratio of fuel and air to achieve optimal energy and fuel efficiency.

The carburetor in a lawn mower regulates the balance of fuel and air based on factors such as engine runtime, mower speed, and type of terrain being crossed.

When the carburetor of a lawn mower is malfunctioning, the engine can still operate, but there will be a noticeable decrease in fuel efficiency and engine power.

How Does A Carburetor Work?

The carburetor operates based on a few basic processes. When the engine starts, the air flowing into the carburetor creates a low-pressure area near the choke plate, which draws fuel from the float bowl into the venturi. The amount of fuel drawn into the venturi is determined by the position of the throttle plate.

When the engine is idling, the throttle plate is partially closed, and the carburetor provides a small amount of fuel and air to the engine.

When the throttle is advanced, the increased airflow through the carburetor draws more fuel through the venturi, providing the combustible mixture the engine requires to run.

The Role Of The Carburetor In Lawn Mower Engines

The carburetor plays a critical role in the proper functioning of a lawn mower engine. It is responsible for controlling the amount of air and fuel that reaches the engine, which determines the engine’s speed and power. A carburetor that is functioning correctly will ensure that the engine runs smoothly and efficiently, minimizing fuel consumption and emissions.

In contrast, a malfunctioning carburetor can result in an engine that has difficulty starting or running, emits black smoke, or burns more fuel than necessary.

The carburetor is an integral component of a lawn mower engine. Understanding how it works and its role in controlling the engine’s air and fuel supply can help keep your lawn mower running reliably and efficiently.

Locating The Carburetor:

Step-By-Step Guide To Finding The Carburetor On A Lawn Mower

To locate the carburetor on your lawn mower, follow these simple steps:

  • First, make sure the engine is cool and the spark plug wire is disconnected.
  • Locate the air filter cover and remove it to expose the air filter.
  • The carburetor is usually located behind the air filter, towards the engine. Look for a round metal part with a few bolts holding it in place.
  • Once you’ve identified the carburetor, you may be able to access it from the top or bottom.

Different Types Of Carburetor Placements On Various Lawn Mower Models

There are a few different places you might find the carburetor on your lawn mower, depending on the make and model. Here are some common carburetor placements:

  • Side-mounted carburetor: Some lawn mowers have a carburetor mounted on the side of the engine. Look for a cylindrical part with fuel and air lines leading to it.
  • Underneath the air filter: As we mentioned above, some lawn mowers have the carburetor located just behind the air filter.

How to Locate a Carburetor on a Lawn Mower
