Lawn Mower Starts Then Dies: Reasons Why How to Fix Them

The sun is out, your grass is long and dry, and all the conditions are perfect for a day of mowing the lawn – only to find that your lawn mower starts then dies shortly after, or doesn’t start at all. This can be a frustrating discovery, and there are a number of different potential causes for a lawn mower that won’t start, or that stops after several minutes of use.

Some of the most common reasons why a lawn mower won’t start include issues with the carburetor, spark plugs, gas tank, oil reservoir, choke, air filter, and muffler. Read through this guide to troubleshoot the root issue of why your lawn mower is failing to start, along with how-to guides on what you can do to try and fix each issue.

Before following these troubleshooting tips, make sure you’re using the correct technique to start your lawn mower properly by following our guide: How to Start a Lawn Mower.

Carburetor is Dirty or Blocked

If your lawnmower’s gas engine is starting then stalling, it’s likely there is an issue with its carburetor. The carburetor is a part of your mower that’s responsible for mixing oxygen and gas in the right proportion to create combustion, regulating fuel flow to the crankshaft that powers the mower’s engine.

A dirty or clogged carburetor bowl disrupts the important job that the carburetor performs. Your engine may be able to start, but soon after you pull the cord, it stalls. This is due to contaminated fuel or fragments of dirt occasionally getting stuck in the carburetor, causing the contaminated fuel to pass through the compressor and stall the engine.

Signs of a Blocked Carburetor

• Engine stalls when mowing lawn
• Engine feels rough during operation
• Muffler emitting black smoke
• Mower consuming more fuel than usual

How to Fix a Blocked Carburetor

You can purchase aerosol carburetor cleaners to fix a dirty or blocked carburetor. These cleaners remove residue from the carburetor bowl using a high-pressure nozzle that sprays a substance that breaks down the carbon particles on the bowl. You can also buy a nylon cleaning brush to use alongside the cleaner to reach every corner of the mower’s engine. We recommend using the STA-BIL Carb and Choke Parts Cleaner along with this Needle and Brush Cleaning Kit to enable you to get as deep a clean as possible when unblocking your carburetor.

Remove the carburetor bowl and screws from the mower

Using a plug wrench, loosen the screws around the carburetor bowl and remove them along with the bowl from the mower.

Clean carburetor bowl, hole and screws

Use the carburetor cleaner to clean off as much residue as possible from the carburetor bowl and screws. Carburetor cleaners with directional nozzles are ideal to reach trickier corners. Clean the hole that sits underneath the carburetor using a thin wire.

Reattach the carburetor bowl and screws

Use your plug wrench again to reattach the carburetor bowl and screws. Make sure to not over-tighten the screws when reattaching the bowl as this can distort the seal.

Spark Plugs are Dirty, Defective or Worn Out

If your lawn mower won’t start or starts then dies soon after, you may have an issue with broken or worn out spark plugs. Spark plugs are responsible for igniting your mower’s engine by supplying electrical currents to the oxygen-gas mixture supplied by the carburetor, creating a small explosion that makes the engine produce power.

Carbon build-ups on the inside of the socket of the spark plugs and the spark plug caps can weaken them and prevent them from creating enough sparks inside the ignition chamber to power the engine. Also, over time, spark plugs end up becoming worn out and may stop functioning properly simply because they’ve reached the end of their lifespan.

Signs Your Lawnmower Spark Plugs are Bad

• You’re able to start the mower’s engine, but it quickly dies out when you try to throttle it. This is a sign that the spark plug is unable to create enough sparks for the engine to run at a high speed.
• Remove the spark plug from the mower and attach it to the inlet, then try to crank the mower’s engine. If you don’t see a tiny spark flash from the tip of the plug near the bent electrode and bottom pin, this is a sign that you need to replace the plug.
• Your lawnmower needs more fuel than usual. This is due to the wasted fuel that isn’t being ignited by the faulty spark plug, and the unburned fuel may produce white smoke.

How to Clean Lawnmower Spark Plugs

Spark plugs that are relatively new but aren’t functioning properly are most likely just dirty and can be fixed with a clean. Carbon build-ups on the plugs will prevent them from sparking, so you may only need to give them a deep clean to get them working again.

Remove spark plugs

Spark plugs are found at the front of the mower wrapped inside a black cable. Find them and use a socket wrench to remove them. Check the manual for your lawnmower to find the correct size wrench for your specific plugs.

Clean spark plugs

Clean off any carbon deposits or dirt using a wire brush and a cleaning solvent, such as this Brakleen Brake Parts Cleaner. Make sure to pay attention to the tip of the spark plug wire, removing any deposits or oil residues completely.

How to Replace Lawnmower Spark Plugs

Older spark plugs with a heavy carbon build-up will need to be replaced entirely. This is an easy and inexpensive process that you can do yourself. Check for a dark heavy carbon residue, or other signs of severe degradation such as cracks, as these indicate your spark plugs are beyond repair and need to be replaced. Ideally, you should replace your spark plugs every season.

Remove old spark plug

Locate the plugs at the front of the mower where they’re wrapped in a black cable. Remove the spark plug’s wire hook and use a socket wrench to remove the plug from its socket.

Measure space between electrodes

Measure the space between the tips of the two spark plug electrodes using a feeler gauge. Take note of the specifications for your mower’s model to know the recommended size of the gap and then purchase the right replacement plug.

If necessary, adjust electrode gap

Adjust the gap between the electrodes if necessary. Use a spark plug gauge to gently bend the curved electrode. When the gap becomes the correct width, the gauge should drag slightly as you pull it through the gap.

Install new spark plug

Install the new spark plug into the socket and reattach the spark plug lead. Take care not to over-tighten the new plug upon installation, only tightening it enough so that it feels snug in the socket.

Gas Has Gone Bad and Formed Residues

Gas that is left sitting in your mower’s tank for long periods will gradually evaporate over time. This leaves behind particles and gummy residues inside the engine that can end up clogging the carburetor, blocking the flow of gas into the engine and preventing it from powering the mower properly.

How to Fix Gas Residue Blockage

If the tank of your lawn mower is under halfway full of old gas, you can try to dilute its impurities by adding new gas to the tank. If there’s more than half a tank of old gas, it would be better to get rid of what’s in there and refill the tank with fresh gas.

Lawn Mower Runs for 30 minutes Then Dies (Why How to Fix)

Lawn mower trouble is the worst, especially when something goes wrong and there is no obvious fix. Whether you’re halfway through mowing or just starting to get your lawn cleaned up on the weekend, it sucks to run into a roadblock. If your lawn mower constantly dies after 30 minutes of use you’re bound to wonder what exactly caused it and how to go about fixing it. Though it might seem like a totally random problem, there are actually a couple of common reasons why this could happen.

Mower Cutting Out After 30 Minutes – Why? (The Short Answer)

If you’ve got a lawn mower that runs for 30 minutes then dies, the most common culprits are: a faulty spark plug or ignition coil, blocked fuel delivery, and air supply problems. A variety of parts are involved here, but the first things you’ll want to check out are the spark plug, carburetor, and fuel cap.

Possible Reasons Your Lawn Mower Runs for 30 minutes Then Dies

In most cases, where you’re getting about half an hour out of your engine at a time, you will probably have to consider more than one issue before you figure out what went wrong. To give you a better idea of what might be happening when your lawn mower cuts out after 30 minutes of mowing, I’ll dig into each of the most likely causes.

Spark Plug or Coil Malfunctions

A spark plug that isn’t producing a strong enough spark or an ignition coil that fails can leave you with a mower that won’t run for longer than 30 minutes. In this case, heat is actually what would cause both a spark plug and ignition coil to fail after about half an hour of use. As the engine warms up, so do all of the parts involved in its operation. All of this heating, cooling, and reheating takes a toll on spark plugs and ignition coils over time. When heated, these parts can expand just enough to disrupt the connection needed to create the spark.

Fuel Delivery is Blocked

Problems with fuel delivery aren’t always very straightforward because there are a number of components involved. With that being said, the carburetor is the most common source of trouble. With a pretty intricate set of parts, carburetors are known to be a headache at times. Whether one of the tiny holes on a jet is gummed up, or debris is floating around in the carburetor’s bowl, it doesn’t take much for the carburetor’s precise air and fuel mixture to get thrown off.

This debris can also cause problems in other fuel-carrying parts. The fuel filter and fuel tank are both parts that can fill up with debris over time. The reason why this can cause a situation where a lawn mower runs for 30 minutes then dies is because any debris may get stirred up from engine vibrations or from hitting bumps in your lawn and settle back down once stopped. When stirred up, these particles can make their way into places they shouldn’t be and stop fuel from flowing.

Air Supply Problems

Air is a crucial component when it comes to igniting fuel to turn an engine over. As air makes its way through your air filter and carburetor, there are a couple of things that can go wrong. The places where the correct air supply can be altered are the air filter, carburetor, and believe it or not, the fuel cap.

A blocked air filter can obviously prevent enough air from getting to the engine which could cause your engine to die. The carburetor, on the other hand, can restrict too much air and also let too much air in. Carburetors have an air screw that is supposed to be set to a certain amount (according to manufacturer specifications) that will allow the perfect amount of air to enter. If this is set wrong you’ll have some problems. Also, there is a gasket where the two halves of a carburetor connect that could be the source of an air leak.

Finally, most lawn mowers have a fuel cap with a one-way vent that allows air in while containing gas fumes. As the mower runs for 20 or 30 minutes, the fuel level will lower. If air isn’t allowed in, a vacuum will be created and gas will stop flowing through the carburetor. After the mower dies and sits for a while, air will find its way back into the tank and allow the problem to happen all over again.

How to Fix a Lawn Mower Won’t Run for Longer than Half an Hour

Now that you have a better idea of why exactly your mower dies after 30 minutes, let’s talk about the fixes. The exact reason why your mower might have this problem can vary and so can the approach you need to take to repair it. I’ll list the things you can do from the most common fix to the least.

Replace the Spark Plug or Coil

The first thing you’ll want to do is inspect your spark plug. Checking to see if it is dirty or cracked is a good first step, but you should also test it to see if it sparks. You just need a socket to remove the spark plug and a pair of insulated pliers to do this.

After removing the spark plug: reattach the spark plug boot, hold the spark plug with the insulated pliers, ground the tip of the spark plug (placing it against a metal part of the engine works well), and have a friend pull the starter rope. If the spark plug is in good condition, the plug should produce a strong spark. If nothing happens, your spark plug needs to be replaced.

After you get a new spark plug, repeat the testing process to make sure the coil isn’t the problem. If your new spark plug doesn’t spark, and you’re sure that you’ve tested it correctly, you’ll have to replace the ignition coil. This is a bit more complicated job that I would recommend going to a small engine mechanic for unless you’re very confident in your abilities.

Clean Fuel Filter and Carburetor

Some lawn mowers have a fuel filter connected to the fuel line that can be accessed, but some lawn mowers have filters inside the fuel tank which cannot be replaced. Check with your manufacturer about this if you aren’t sure where yours is.

If you can access it, replacing the fuel filter is very simple. You’ll just need to remove a couple of hose clamps, buy a new filter, and install it. I would recommend doing this first if possible because cleaning a carburetor is a bit more labor-intensive.

However, if the fuel filter doesn’t solve the problem, you should remove your carburetor and clean it. I like to buy a can of carb cleaner that has a small straw included so that I can direct a pressurized stream through all of the jets and hard-to-reach places.

If you disassemble your carburetor and notice that it is extremely dirty or has a ton of buildup, you should soak the entire thing in carb cleaner or consider replacing it. If you don’t have a lot of experience working on small engines, you might also save a good chunk of time by having your local mechanic take care of it for you.

Correct the Air Supply

Making sure that the air supply side of things is working as it should requires you to look in a few different places. I would start with your air filter. If you have any doubts about whether it is in good shape or not, just replace it. Filters are inexpensive and should be swapped out once every season anyways.

After taking a look at the air filter, the next place I would investigate is the fuel cap. A fuel cap that has been damaged or isn’t allowing air to enter the fuel tank is a really common cause for a lawn mower that runs for 30 minutes then dies. Make sure that the fuel cap is in good condition and has a vent that works properly.

Lastly, take a look at the carburetor. This is where all of the air mixing happens. Start by making sure that all of the carburetor gaskets are well fitted and not cracked. If they look good, check out the air screw. This screw is usually found on the bottom of the carburetor near where the gas enters it. To adjust the screw you will need to find out where it should be set according to the manufacturer. After figuring out the number of turns it needs, you can adjust it accordingly with a flat head screwdriver.

Lawn Mower Won’t Stay Running: Why And How To Solve?

So, your lawn mower keeps dying on you. Well, just like anything with a motor, sometime your mower will have issues that cause it to stall and cut off. If you are having that issue with your mower, then you are in the right place.

In this article, we will look at the reasons why your mower won’t stay running and also give you the solutions for them. Keep reading to see all the possible reasons why your lawn mower is stalling.

Possible problems cause Lawn Mower Won’t Stay Running

Before going into an in-depth analysis of each issue, we will list out the potential problems below. That way if you have an idea of what the issue might be you can jump to that section first to save yourself some time. Do you check the lawn tractor battery first? It can be a problem.

The reasons why your mower might not stay running can fall into the following areas:

• The Fuel System
• The Carburetor
• The Ignition System
• The Cutting System

You will need to clean it out, so air can get thru. After doing that the problem should be resolved. If something else is dirty though and the gas cap is not the issue, then you will have to look farther.

Sticking with airflow, the next thing you can check is the air filter. This should be clean and not have debris or blockage. Also, if it has oil in it, then that is a problem too. If it does have a blockage or is dirty, then you will need to clean it out or replace it.

Air filters are not expensive, so it is a good idea to replace them with a clean one regularly or at least clean it out since it is easy to get too. If it is not the air filter that is dirty, then it might be the fuel lines that are dirty.

If that is the case, you will have to drain the fuel and then remove the lines. Remember to drain both the tank and the carburetor. When removing the lines inspect them and see if you see any build-up. If you do clean it off or replace the lines.

2/ The Carburetor

The issue may be in the carburetor itself though. It might be the thing that is dirty. If you are draining the fuel, then go ahead and take the time to check the carburetor. See if you can see any build up of gunk or deposits in it.

If you do be sure to clean it. Also, remove the fuel filter from the carburetor and see if it is dirty. If it is then clean or replace it as well. Same as the air filter, the fuel filter is pretty easy to get to and is cheap, so stay on top of replacing it and making sure it is clean. This will keep other parts of your mower running longer.

When cleaning the carburetor, it is essential to do it properly. You should use carburetor cleaner and spray it down thoroughly. Sometimes though even the cleaner won’t be able to get all the build up off. This is because fuel residue can be hard to remove.

If you can’t get the carburetor clean, then you can rebuild it with a kit from your mower manufacturer. Sometimes though it isn’t worth it to rebuild. This may be because you don’t have the time or the skills to do it.

If that is the case, then you can just buy a whole new carburetor and replace the old one. No matter if you are cleaning, rebuilding, or replacing the carburetor be sure to clean out the fuel lines as well.

3/ Ignition System

The next reasons why your mower might not stay running could come down to the ignition system. This is similar to the fuel system and could be lumped in there. The ignition system for our purposes is where the spark occurs to ignite the fuel and provide power to the mower.

The part of the ignition system that we are worried about is the spark plugs. Old wore out, and dirty spark plugs can lead to the engine dying. They may work good enough to start the mower, but then misfires might start to happen leading the mower to shut off. If you hear misfires, then checking the plugs should be one of the first things you do.

To make sure the plugs are good you first need to pull them from the engine. Next, you can visually look at the electrode. If it looks dirty, then you can try cleaning it with an emery board, but if the electrode is already too thin, then you will need to replace that plug.

Also, it is a good idea to replace all the plugs if you are replacing one, so you know that they are all good. The electrode might not be dirty though, but the problem could still be the spark plug. If the gap on the plug is too big or too small than that can be an issue too.

You will need to look up the specifications for your mower and the gap it should be and then use a gapping measure to measure the gap. If it is off, then you need to replace the plugs.

4/ The cutting system

The last area that can cause your mower to stall while mowing is in the cutting system. What we mean is if you are cutting thick or tall grass, then it might be bogging down the blades and causing the engine to stall.

If you can tell that the mower is having trouble cutting on the level you have it set too, then you will need to raise the deck. If raising the deck doesn’t help, or the grass isn’t that tall or thick, then the problem might be in the blades themselves or under the deck.

If the blades are dull, then they will not cut well, and that can lead to the mower stopping. You will need to get under the deck and remove the blades to sharpen them. Once they are sharp, that should solve the problem.

If your blades are sharp though, then they might be getting bogged down for another reason. That other reason is you could have a lot of grass built up under the deck. If that is the case, you will need to get under it and clean it out.

If you are sharpening the blades or cleaning the deck, then you should go ahead and do both things since you are already under there. It doesn’t take that long to remove the blades to sharpen them if you are already cleaning under the deck and it doesn’t take that long to clean under the deck if you are already sharpening the blades.

By doing both, it will save you time later and make sure you get the best cut possible.

Conclusion

So, after reading this, you now know all the possible reason why your mower won’t stay running and also the solutions for them. The issue could be in air flow or fuel flow. In either case, you will need to clean those systems out or check its battery.

It can also be due to bad ignition. If that is the case, you will need new spark plugs. Lastly, it might just be that the blades are dull, under the deck is dirty, or the grass is too thick and not be a mechanical issue at all. If it is from that, then you will need to sharpen the blades and clean under the deck or raise the deck.

Luckily most of the reasons why your mower is stalling are easy fixes if you know what to check, and now that you have read this you do, so you are well on your way to fix your mower that is dying and not has to worry about the engine stopping in the middle of cutting again.

Reasons Why Your Lawn Mower Starts Then Dies Right Away?

Every lawn owner has had trouble with their mower at some point. One of the most common problems is that the lawn mower starts then dies right away. It has an easy fix. So, if you’re one of those lawn owners who’s been going mad over this problem can finally relax.

Whether you use a single or a twin-cylinder engine, it seems like they all have the same problem with starting up and shutting down at some point in their lives.

Reasons Why your Mower Starts then Dies Right Away:

Poor gasoline, too little or too much oil, a clogged carburetor, a clogged air filter, poor ignition oil, a poor fuel cap, a plugged fuel line, a clogged cooling system, or a dirty filthy plug can all cause your lawn mower to start and then die right away.

Your Lawn Mower Doesn’t have Gas.

Surely you know that a gas-powered mower needs gas to start. So, before you start panicking, check the gas tank. If it’s almost empty or fully empty, then fill it up. If you see that the fuel gauge isn’t working, then you had a gas leak. Another reason can be that you just forgot to put gas in your lawn mower. Most people do not remember to check if it’s running out of petrol.

Old or Bad Fuel in your Lawn Mower

If the fuel in your lawn mower is old or bad, it could stop working after it has been used. Most gasoline only lasts a month before it breaks down and stops working. Since the chemicals that are applied to today’s gasoline start to break down, the mower starts losing its capacity to run hot and well.

Most of the produced gasoline nowadays has ethanol mixed in it. Fuels that have ethanol soak up water from the atmosphere. As a result, the fuel system could be clogged up if water evaporates and leaves a residue within the fuel tank.

A Plugged Air Filter

Sometimes you’ll see that you have tried looking for the problem everywhere but cannot find it. Most likely it’s your lawn mower’s air filter. When a lawn mower’s air filter gets clogged, it stops working in the middle of the work.

Clogged Fuel Filter

If there is dirty, old, or polluted gas in your mower’s tank, the gasoline filter could get clogged. This stops enough fuel from getting to your engine so that it can keep running.

The Lawn Mower’s Fuel Line is Blocked

Old gasoline can leave oil and sticky deposits in the fuel system, which can make them hard to move. Also, gasoline lines can get pinched or kinked. The lawn mower that you use will die because it doesn’t have enough gas.

The Fuel Pump on Your Lawn Mower Broke

If your lawn mower’s gas tank is smaller than your mower’s carburetor, your mowing machine will have a fuel system that sends fuel to the carburetor to help with fuel flow. Most riding lawnmowers now have fuel systems, but most push lawn mowing machines do not.

Over time, fuel could cause the mowing pump seams to break. If your pump starts spilling fuel, you could tell it’s damaged or broken. but it’s hard to tell if there’s damage on the inside, you’ll have to evaluate it to verify that it works.

Your Lawn Mower’s Carburetor Might be Dirty

If your lawn mower stops in the middle, then maybe your mower’s carburetor is clogged up. Your mower’s carburetor is meant to control how much air is mixed with the right fuel amount to make combustion happen.

Your Lawn Mower’s Crankcase has an Excess Level of Oil

If your lawn mower has an excessive amount of engine oil, it might not work well and shut down in the end. If there is an excessive level of oil in the engine, it won’t be able to pull in clean air, and the smoke will clog up your lawn mower’s air filter.

So, the engine might pull oil and air from its crankcase, which could clog the air pump. If there isn’t enough air, the mower might stop working in the middle.

Low Oil Level in Lawnmower

Oil is for greasing the parts inside the engine. When there isn’t sufficient oil, friction builds up, and heat from it stops the mower. Such a high temperature can thicken and melt the engine parts.

A Broken or Clogged Spark Plug

Your engine can stop running if the spark plug is clogged. It makes enough spark to get your mower going, however, it might not be enough to keep it running. Test how good your spark plugs are. If the wire(s) to the spark plug(s) seem to be loose or the placement is wrong, your mower may have trouble starting and running sometimes.

Wrong Placement of the Mower’s Choke

Almost all lawnmowers have a part called a choke. While your lawn mower’s engine is heating up, the choke’s job is to stop air from going into the engine is heating up, a choke is used to stop air from going into the fuel tank so that more fuel can get in.

The choke on a lawn mower is used to start an engine that is cold. If you leave the choke on after starting your mower, the engine gets too much gas and not enough air, which shuts it off.

Your Lawnmower’s Fuel Cap Might be Clogged or Broken.

If the fuel cap is broken or you have a clogged vent, it’s only normal for your engine to die because it doesn’t get enough fuel. If the cap won’t let the air out, a vacuum is supposed to be formed in the tank, making it impossible for fuel to get in.

Faulty Lgnition Coil

When a lawnmower gets hot, ignition coil wires come apart and cause a short. Whenever this happens, your mower’s spark plugs can’t get enough voltage to make a spark. This could make your mower stop working after some time.

Blocked or Broken Cooling System

Grass and mud damage the cooling fins. Once this happens, the fins can’t keep the engine block cool as it cannot move air around it. If this happens, your mower might get too hot and stop working while cutting the grass.

A Useless Lawn Mower Deck

When there is a lot of grass and other stuff stuck on the mower deck, your engine will start working harder. When the blades turn through a great bunch of debris, they put more strain on your engine which can cause your mower to stop working in the middle.

Maintaining a beautiful lawn can be a daunting task, especially if you lack the appropriate know-how and tools to handle the challenges that may crop up. Fortunately, LawnAsk is here to offer you an all-encompassing resource that covers everything you need to know about lawn care.

Why Does My Ryobi Lawn Mower Keep Shutting Off? (Solved)

Ryobi makes some fantastic mowers, and I have reviewed some of them here.

But I have seen one question come up fairly regularly from those who own them.

Why does my Ryobi lawn mower keep shutting off?

It does seem to be a common problem.

Thankfully it is one that can be resolved.

So we take a closer look at the possible reasons for it here.

Why Does My Ryobi Lawn Mower Keep Shutting Off?

The common recurrence of Ryobi mowers suddenly shutting off is usually down to a poor design of the handle affecting a safety switch that stops the mower from working. Often tightening up the bolts connecting the handles to the mower can fix the issue. If your mower is within warranty contact Ryobi who should be able to work with you to resolve the problem.

REASON #1: It is a Problem With the Handle

If you are having issues with your Ryobi mower randomly shutting off without warning, the number one place you want to look to resolve the issue is the handle of your mower.

It seems to be the source of most problems.

If your grass is too long and thick, and you go too long between mows the blade might get stuck on the accumulating grass clippings and stall.

The mower will automatically sense it is being overworked and intentionally stall the mower to prevent the motor from being blown.

Make sure you don’t leave your grass too long between cuts.

Final Thoughts

We’ve covered it in detail here, and on the infographic above, but if you are having problems with your Ryobi mower stalling the most likely cause of it is the handle and the safety switch.

They work in conjunction with each other and have been purposefully designed to ensure you can’t accidentally start your mower without the handle being properly engaged.

Unfortunately, the design ruins what are otherwise very good mowers!

If your mower is still within its warranty get in touch with Ryobi who should sort the problem out for you.

Or simply bear this in mind when you make future purchases, as it is a very frustrating problem to experience.

There are some great lawn mowers on the market these days, so you shouldn’t have to put up with a recurring issue like this.
