Lawn mower making noise. Car Sounds Like A Lawn Mower – What Could Be Wrong

Car Sounds Like A Lawn Mower – What Could Be Wrong?

If you ever heard a noise that resembles a lawn mower come from your car the moment you stepped on the gas pedal, it’s highly likely to scare and trouble you. Fear not, however, as this merely indicates something is wrong with your vehicle. And as such, we asked automobile experts for their opinion on the subject.

Most car experts would tell you that several factors could cause your vehicle’s strange lawn mower noise. The following causes are:

If you encounter any of these, it’s best to take your car to a local automobile shop to avoid further damage.

This article will explain each cause and what led to that point. We will also discuss the dangers that come with each one and how to fix them. So, continue reading further to find out more.

Why Does The Car Sound Like A Lawn Mower?

In this section, we will further discuss the causes of what makes your car sound like a lawn mower. Although several reasons can produce that sound, we only FOCUS on six major ones.

Leaking Exhaust

The exhaust is an essential component of any car and is responsible for two primary roles. First, it transports burned gasses out of the car’s system. Second, it catalyzes those gasses into less damaging substances to avoid harming the environment.

Because of these activities, it’s common for the exhaust to wear down over time and break. Also, because hot gasses pass through it, the underlying stress that accompanies it causes frequent expansion and contraction. And when that happens, the pipe eventually weakens and starts showing signs of cracking.

What’s more, the exhaust also lets out vapor, causing the metal pipe to rust as well. And not only that, external factors such as snow, dirt, rocks, and water can cause significant damage as well.

Physically checking your exhaust is the best way to determine if you have an exhaust leak. Start by moving your hand underneath the exhaust pipe without touching it to prevent burning your hand.

From there, you should be able to tell if there’s a leak if the gasses are blowing against your hand. And if there is a leak, it’s best to drive your car to the nearest automobile shop.

Usually, a simple weld would help fix the issue. In some cases, you may need to have some parts replaced. However, that’s a small price to pay.

An exhaust leak is dangerous because you can’t see or smell the gasses leaking into your vehicle’s cabin. When that happens, you can either get sick or, worse, lose your life.

Blown Head Gasket

The head gasket is a barrier between the engine and the car’s cylinders. Like the exhaust system, a head gasket has two primary roles within the vehicle.

First, it prevents the combustion gasses from escaping the gas cylinder and entering the car’s cooling system. Second, it keeps both coolant oil and water from mixing and seeping into the various cylinders of the vehicle. This makes the head gasket responsible for cooling the car’s engine and maintaining its efficiency when it comes to speed and power.

The main reason this leads to a blown head gasket is overheating. This would cause the head gasket and the engine to contract and expand at different rates. When that happens, the gasket would no longer fit like normal in between the engine and the cylinder, producing that lawn mower-like noise due to a pressure difference.

When the car suffers from a blown head gasket, it’s best to have an automobile expert check it for you. One, the constant noise that it makes would significantly affect your hearing. And two, harmful gasses would escape from the gasket and leak into your car’s cabin.

Additionally, if you let this issue persists, it will significantly damage your car’s engine. When that happens, a repair might not be an option anymore. You may need to buy a new car at that point.

Faulty Wheel Bearing

You might be familiar with what a wheel bearing is because of several products, like fidget spinners and yo-yos. Incidentally, your car’s wheels are also tightly packed into a hollow metal cylinder.

The wheel bearings provide stability and reduce friction when the car is on the road. Because of this, they are often the subject of wear and tear, like many of a car’s components.

Over time, these wheel bearings loosen up, which causes them to produce noises like a lawn mower. One way to determine whether they have loosened is to roll each wheel independently. From there, you should be able to hear bearings hitting one another.

The danger of having loose wheel bearings is that they can suddenly cause the car’s wheels to stop. On the road, that risks a terrible accident.

It’s best to have the whole wheel replaced immediately. Failure to do so can lead to losing your life.

Worn Out Tires

Check the tires if you hear your car producing noises like a lawn mower. Worn-out and under-inflated tires can cause this issue.

The dangers that come with having worn out and under-inflated tires are plenty. They not only provide less gripping power on the road, but they also significantly impact the car’s braking ability.

These issues can also lead to a blown tire; when that happens, an accident will follow. So, changing your car’s tires every six years is imperative to keep them inflated continuously.

Engine Failure

This is often the result of a faulty spark plug or a defective oxygen sensor. Following this, one of the cylinders cannot produce any power. This causes fuels to become unburned, leading to the rumbling noise of a lawn mower.

Driving on the road with a faulty engine is dangerous as this can easily cause your car to stop. When that happens, this can cause a significant accident on the road.

Listen carefully to the sound it produces to determine whether there’s a problem in the engine. If it’s making noises you are unfamiliar with, have a car mechanic look into it.

Old Differential Fluid

The main job of the differential fluid is to reduce friction inside the gearbox. Generally, replacing it after 30,000 miles is the norm. However, it’s best to consult your car’s manual for the appropriate time.

To find out whether the fluid is the cause of the noise, first learn whether your car uses front or rear differential fluid. Then, switch gears depending on where the fluid is located and listen carefully.

The dangers of aged differential liquid are that it causes the gearbox to overheat and, in turn, break down. Not only that, but it also causes your car to be unable to make corners on an easy road. And, in the worst scenario, it causes it to halt.

Prevent incidents like this from occurring by regularly changing the differential fluid. Additionally, pay a visit to a mechanic to have the gearbox inspected.

Is It Possible To Drive With An Exhaust Leak?

Your vehicle will still run with an exhaust leak, but you shouldn’t take it out for a drive. Harmful gasses can easily seep into the car’s cabin without you ever finding out.

Not only that, just the slightest exposure to these gasses can cause you to have severe headaches. In some cases, it would cause you to pass out. That would then lead to a vehicular accident.

What Is The Cost Of Repairing An Exhaust Leak?

The price varies greatly depending on the extent of the damage. A simple leak or fracture would cost you around 50.

However, that number could go upward by 1,000 for a broken catalytic converter. So, it’s best to have the issue resolved immediately once detected to avoid burning a hole in your wallet.

In Closing

When your car starts producing noises like a lawn mower, remain calm and observe the situation. As mentioned earlier, the causes are a leaky exhaust, a blown head gasket, faulty wheel bearings, worn-out tires, engine failure, and old differential fluid. Then, immediately have an automobile mechanic check on your vehicle to have it fixed.

Car Sounds Like Lawn Mower (Causes and Fixes)

Hearing your car sound like a lawn mower is certainly concerning, especially if you haven’t experienced it before. Fortunately, there is no need to worry because it will be easy and cheap to fix regardless of what’s causing it.

If your car sounds like a lawn mower, it means one or more cylinders are not firing. Only three things can cause that, including bad spark plugs, faulty ignition coils, or, if you drive an older car, bad spark plug leads. Swapping out the faulty component will do the trick and fix the weird lawn mower noise your vehicle is creating.

What Makes the Car Sound Like a Lawn Mower

We already mentioned that the car sounds like a lawn mower because one of the cylinders isn’t firing. Specifically, the sound is an unburnt air/fuel mixture being pushed out of the exhaust at high pressure.

The reason you can hear this with lawnmowers is that the exhaust is much shorter, making the exhaust gases sound much more pronounced. Also, the engine vibration is much more severe with a dead cylinder, making the sound resemble a lawn mower even more.

How to Find Which Cylinder Is Not Firing

pulled from the Amazon Product Advertising API on:

Product and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on [relevant Amazon Site(s), as applicable] at the time of purchase will apply to the purchase of this product.

Even though we already mentioned what’s causing the symptom at hand, and we will cover it in more detail later, you still need to know precisely which cylinder is dead. That way, you avoid replacing the wrong part, and you save a significant amount of time, for example, replacing one spark plug at a time until the engine starts running right.

To diagnose the issue properly, you need an OBD2 scan tool which, luckily, you can buy for around 20-30 on Amazon. Alternatively, you can visit a local AutoZone shop, where they will scan the fault codes for free. If you opt to do it yourself, you will also need to know how the cylinders are numbered in your vehicle, but you can easily find that information online.

Once you scan the fault codes, you are looking for P0301 to P0312 codes, each of which represents a misfire of a specific cylinder. For example, a P0304 means cylinder number four is misfiring; a P0307 means cylinder number seven is misfiring, and so on.

Fault Codes

  • P0301 – Cylinder #1 Misfire
  • P0302 – Cylinder #2 Misfire
  • P0303 – Cylinder #3 Misfire
  • P0304 – Cylinder #4 Misfire
  • P0305 – Cylinder #5 Misfire
  • P0306 – Cylinder #6 Misfire
  • P0307 – Cylinder #7 Misfire
  • P0308 – Cylinder #8 Misfire
  • P0309 – Cylinder #9 Misfire
  • P0310 – Cylinder #10 Misfire
  • P0311 – Cylinder #11 Misfire
  • P0312 – Cylinder #12 Misfire

Lawn Mower Engine Noise: Causes Fixes

Bad Spark Plugs

The spark plugs should be the first thing you check because, if nothing else, they are the cheapest to replace. Once you know which cylinder is misfiring, visit a local auto parts store and get a new one, or better yet, replace all of them if it’s been more than 50,000 miles since you last replaced them.

Even the highest quality spark plugs are rarely more than 7-9 a piece, and that’s if your vehicle requires platinum or iridium spark plugs. The standard copper ones, on the other hand, are more like 2-4. That means you can replace all of them on a four-cylinder engine for 15 to 30. If you want to save some money, you can replace them at home using the following guide and video.

How to Replace Spark Plugs

  • Get a socket wrench set with a deep spark plug socket.
  • With the engine off, open the hood.
  • If there are any plastic covers over the engine, remove them.
  • If your car has a coil-on-plug ignition, you will need to remove the coils. They are usually held down by hex key bolts.
  • Remove the coils over the spark plugs or pull the spark plug leads out if that’s what your engine has.
  • Use the deep socket to remove spark plugs and replace them with new ones.

In this video, you can see how to replace spark plugs on an engine with coil-on-plug ignition. It’s even easier on the engine with spark plug leads because they come right off when you pull them.

Faulty Ignition Coils

By ignition coils, we mean coil on plug ignition coils. Those are individual ignition coils sitting on top of every spark plug instead of spark plug leads. The ignition coils basically serve the same function as earlier distributors. But while distributors are mechanical, coil-on plugs are controlled by the ECU and also serve as voltage transformers bumping the standard 12 volts to anywhere between 12,000 and 25,000 volts.

Unfortunately, these ignition coils are susceptible to premature failure, especially in cars made before 2010. In some cases, they may even snap in half, and needless to say, if the coil fails, there is no power going to that spark plug, and your car will sound like a lawn mower as a result. Also, a single coil will run you 50 a piece on average, but at least they are easy to replace, so you can save some money that way.

How to Replace Ignition Coils

  • With the engine off, open the hood and secure it.
  • Remove any plastic covers that may be over the engine. These are either clipped in place or held down with a couple of bolts.
  • Once you can access the coils, check what kind of bolts are holding them in place, it’s hex key bolts most of the time.
  • Unplug the coil connector.
  • Unfasten the coil bolts, remove the coil, and replace it with a new one in reverse order.
  • In case you are replacing more than one, do it one by one to avoid mixing up the coil connectors.

In this video, you can see just how simple the whole process is.

Bad Spark Plug Leads

In case you drive a relatively older car, chances are it still has a mechanical distributor or stand-alone ignition coils (wasted spark ignition coil). Since in both systems, the ignition coil sits away from the spark plugs; it needs spark plug leads to transfer electricity to the spark plugs so they can fire. Spark plug leads are essentially thick, high voltages wires.

The spark plug leads are somewhat problematic, especially if they were replaced with low-quality ones. And if one of the leads stops doing its job or starts shorting the spark to the engine cover, the affected cylinder will quit firing, resulting in an engine with the symptom at hand.

Spark plug leads are always sold as full sets, and if one spark plug lead is bad, chances are high; the rest of them are on the way out, so it’s a good idea to replace them all at once. A set of new leads for a four-cylinder car costs between 20 and 50, while a set for a V8 engine costs between 35 and 100.

But it’s a good idea to get higher quality ones because off-brand spark plug leads typically start causing misfires after no more than 15,000 to 20,000 miles.

How to Replace Spark Plug Leads

  • Take the new spark plug leads out of the box and lay them out so you can see the length of each one.
  • With the engine off, open the hood and secure it
  • Remove any plastic covers that might be over the spark plugs.
  • Remove one spark plug lead and compare its length with the new one so you find the correct replacement. You can unplug the lead on both ends by pulling on it, although some might be stuck, in which case a pair of pliers will come in handy.
  • Install the new spark plug lead and repeat the process by replacing the leads one by one so you don’t mix them up because each leader has to go to a specific cylinder/spark plug; otherwise, the engine won’t run, or you will cause further damage.

This short two-minute video demonstrates the whole process.

What Are the Three Types of Spark Plugs?

The three main types of spark plugs are copper, iridium, and platinum, and the two less popular ones are nickel and laser iridium. All these types refer to the positive/center electrode material. But other than the electrode materials, spark plugs can also be divided by size, heat ratings, thread types, gaps, etc.

How Long Do Spark Plugs Last?

Standard copper spark plugs usually last between 15,000 and 30,000 miles. However, platinum spark plugs can last up to 60,000 miles, while iridium ones can go as much as 100,000 miles and sometimes more.

Can You Clean and Reuse Spark Plugs?

Yes, you can clean and reuse spark plugs, and that’s an especially good idea if your car has had other problems that can affect the air/fuel mixture. However, cleaning the spark plugs will only produce a noticeable effect if they are relatively new because cleaning them won’t restore them in any way.

How Often Do You Need to Replace Ignition Coils?

Ignition coils don’t have a set service schedule meaning you should only replace them once they fail. Depending on the type of ignition coil, they can last up to 150,000 miles. However, you can expect that much only from older wasted spark ignition coils because newer coil plug coils rarely go over 100,000 miles without issues.

Should I Replace All Ignition Coils at Once?

No, there is no need to replace all ignition coils at once, but it is a good idea. If one ignition coil has failed, chances are high that others are on the way out, so if you want to avoid surprises in the near future, you should replace them all at once.

How Often Should Spark Plug Leads Be Changed?

Spark plug leads should be changed only when they fail because there is no set service schedule for them. But if you want to be safe, you can replace them every other time you replace the spark plugs.

Are All Spark Plug Leads the Same?

No, not all spark plug leads are the same, although they are interchangeable for the most part. All spark plug leads fit the same spark plugs, so it’s only an issue of length and the shape of the pipe whether or not they will fit. But keep in mind that the spark plug lead thickness and materials can be different.

How Many Ignition Coils Does a Car Have?

A car can have anywhere between one and 12 ignition coils. Older vehicles typically have only one ignition coil, while newer models with wasted spark systems can have one ignition coil for every two cylinders (eight-cylinder engines would have four ignition coils in that case). And in case your car has a coil on the plug ignition system, it will have one ignition coil for every cylinder.


In the end, we can say with utmost certainty that the reason your car sounds like a lawn mower is that one of the cylinders isn’t firing, and there is a fault somewhere in the ignition system of that cylinder – a faulty spark plug, spark plug leads, or coil-on-plug ignition coils. As a first step, scan your car for fault codes, so you know which cylinder is misfiring before you start your inspection.

Finding and Fixing Mower Noises

Is your mower making a strange noise? As the mowing season draws to a close, your mower has more and more hours put on it since its spring service, making it more likely that something will need attention. Finding the source of noises and correcting them now can help you avoid costly repairs later on.


Honda makes some of the quietest small engines on the market, but they still produce enough noise to cause hearing damage. Hearing protection should be worn when using a mower just as you would with any other outdoor power equipment, but added noise may be a cause for concern.

If everything seems fine and the engine is just unusually noisy, check the muffler. Before pulling it off of the motor, wait at least a half hour after running the mower to let it cool down completely. Inspect the muffler for holes, and make sure the seal between the exhaust and the engine is intact.


While most greased components are sealed, other areas may occasionally need a light oil or silicone lubricant applied to keep them moving freely. This includes the controls, cables, wheels, and the handle, both where it bolts to the mower and where it folds for storage. Squeaking noises from the engine can be caused by grass and debris packed against the flywheel or engine shaft, or it could indicate a slightly bent shaft.

Some models have sealed cables and wheel bearings which won’t need to be greased. If the squeaking is coming from one of these wheels, spin it to make sure it’s moving freely. If it’s not, the wheel will need to be replaced.


Engine vibrations can loosen bolts and nuts over time. Go over your machine and check the tightness of each fastener. Here’s where to check, from the most likely to the least likely source:

– Handle – Controls – Muffler cover – Engine cover – Wheels – Deck


Some vibration is normal, but excess vibration is usually tied to the mower blade. Remove the blade from the mower and check for bends and cracking; if either is present, the blade needs to be replaced. To check the balance, hang the blade on a nail by its center hole. If one side sits lower, file off a little of the surface until the blade sits even on the nail.

Honda’s MicroCut system uses two blades and a set of washers that need to be installed in a specific order to prevent vibrations. The small blade should be put on first with the top flat edge pointing to the left, while the lower blade goes underneath with the curved ends pointed upward and the top edge to the right. There should be one washer between the blades and a second washer between the blades and the bolt.

The blade bolt on all mowers needs to be tight enough to stay on and prevent the blade from coming loose, but not so tight that it stretches the threads. Torque specs for this bolt can be found in the owner’s manual.


Even on engines equipped with Oil Alert, it’s a good idea to start with checking the oil, as a lack of lubrication can cause knocking and quickly lead to engine damage.

Light pinging is normal on engines under a heavy load, but if it occurs constantly, it’s probably caused by the fuel. If you’re running fresh automotive gasoline, it should have a high enough octane to keep this from happening, but its knock resistance can drop as it ages and degrades. Always use fuel within a month from purchase, or three months if treated with a stabilizer. “White gas,” commonly used in camp stoves, is gasoline, but it has a much lower octane rating. Even pouring a little from a leftover tank can reduce the fuel’s antiknock properties that it can cause pre-detonation.

If the fuel is fresh, check the ignition system. The spark plug should be clean and have the correct gap. If the wrong model of a spark plug is used, it can heat up to the point that it ignites the gas before the spark does. The coil may also need to be repositioned to change the ignition timing. Excess carbon build-up can also cause pre-ignition, but usually, this is only seen on motors that have been used for hundreds of hours.

Lawn Mower Engine Makes Popping Sound: Reasons and Fixing Tip

Did you hear the Lawn Mower Engine Popping Sound? Well, this could seem dangerous. Relax because the backfiring or popping sound made by your mower engine is not serious but it does point to other issues that need to be addressed immediately.

So what exactly is this popping sound and why is it caused? Also, what can be done to fix it? Get all the information in this article.

What is Popping Sound on Lawn Mower?

A popping noise or a backfire is caused when the gasoline ignites outside the engine’s combustion chamber. Your mower may be working properly with no trouble and then you unexpectedly hear the backfiring. This explosion can distress you but there is nothing to worry about. However, if left unattended, then the cause behind this backfire could get hazardous for your mower engine.

You must delve deep to figure out what caused the engine to backfire. Once you understand the cause, fix it so that your mower can work normally again.

The popping sound usually occurs when you turn the engine on or off. Having some basic information about the popping sound and ways to deal with it does help.

lawn, mower, making, noise, sounds, wrong

Why did My Lawnmower Engine Make a Popping Sound?

The mower engine is a small combustion engine placed internally. Power gets produced in this combustion engine through the air-fuel mix combustion. This power production can take place in the 2-stroke and the 4-stroke engine. In both cases, it is the air-fuel mixture combustion that creates a spark to ignite the moisture which causes an explosion and releases energy.

The fuel combustion takes place in the combustion chamber in a controlled environment. If the fuel burns elsewhere then this causes a popping sound.

The popping or the backfire sound is heard when the fuel comes in close contact with the spark outside of the engine combustion chamber. The sound could be caused because of a problem with the fuel or the engine.

Fuel Related Issue and Fix

There is fuel in the engine combustion chamber that needs air or oxygen to burn. Every engine is designed to get the right mixture of air and fuel in the combustion. All the strokes need to be perfectly timed for complete fuel combustion, smooth operation of the machine, and maximum release of energy. If there is an incorrect proportion of the air-fuel mixture then this causes many problems like the engine burning up smoke.

The timing of all the processes in the combustion chamber is important. If a process happens early or late then this causes problems. If there is an incorrect proportion of air-fuel mixture then this disrupts timing.

If there is a lot of air in the combustion chamber the engine does not create a spark because there is enough power to ignite the fuel for some time. The ignition is delayed but the other processes occur in their regular way. This makes the fuel pool in the low spots with the exhaust. The fuel gets ignited outside of the combustion chamber that produces an explosion or a popping sound.

At times the fuel escapes the engine’s cylinder before the valve closes. This could also occur during the exhaust stroke and then the fuel enters the exhaust or the engine. If there is a good amount of unspent fuel that enters the engine and comes in close contact with the spark then this makes it ignite and causes the engine to make a small popping sound.

In a nutshell, if the fuel combustion occurs anywhere apart from the combustion chamber in the engine or the exhaust then this will cause the popping sound.

How to fix it?

If the air-fuel mixture has more amount of air then this is called the low-pressure fuel. If the mower engine is backfiring then this could be because the low-pressure fuel is getting pumped into the combustion chamber of the engine. An old fuel pump or fuel filter could be causing low-pressure fuel.

All that you need to do to rectify the problem is to replace the old fuel filter and repair the fuel pump. If the problem was caused because of the low-pressure fuel then this will fix the issue.

Engine Related Issues

The timing of the engine processes is crucial so that the mower functions smoothly. If there are some issues with the engine that mess with the correct timing then this will cause a popping sound.

Check the timing of the motor to see if the engine is backfiring. If there is an issue with the timing of the motor then this will cause the engine to ignite the fuel even though the internal valves are open.

After using the engine for a long there could arise a problem with the timing of the valve and the engine that could get disrupted. This could also occur because of a simple and basic chemical malfunction.

The problem should be fixed without delay so that the exhaust and engine do not get damaged further to become unrepairable.

How to fix it?

lawn, mower, making, noise, sounds, wrong
  • An engine tune-up restores the valves and the engine to its correct time setting. This will let both the valves open and close at the right time that and not let the fuel burn in the engine.
  • Spark plug cleaning or replacement helps. Just clean the plug chamber or the plug wire which will ensure the right timing of ignition thus preventing the backfiring sound.
  • Keep the fuel filter clean and replace it each year. Take guidance from your owner’s manual to understand which fuel is best for your mower.

Significance of Timing on Lawn Mower Popping Sound

Now that we have dealt with the issues that could cause an engine to backfire let us understand what significance does the popping sound timing hold.

During the start

If the lawnmower makes a popping sound when you start it then this indicates a damaged mower. Many mower parts safeguard the expensive parts. Like the flywheel will take damage to protect the expensive crankshaft. If your mower runs on a large rock then this can cause the flywheel to break and fail to engage causing the engine to make a popping sound when you start the mower.

A mower that has its flywheel broken will not start automatically. If the mower backfires then this indicates damage and you should take it for professional repair.

What Caused the Lawn Mower Engine Knock?

During the shut-off

Sometimes you may hear the pop sound when you turn off the engine or when your mower is just lying idle. This happens when you slow down the engine fast. The speed of the engine builds up when it is in operation and when it is slowed down quickly then it pushes the gas in the muffler. This gas gets ignited and causes the popping sound.

To reduce the chances of such popping sounds you should reduce the mower speed gradually and let the motor stand idle for around 15 minutes before you turn the engine off.

Engine overheating is another reason why your mower is backfiring when you shut it off. Increasing the flow of air to the engine can reduce it from overheating. If you hear the popping sound during the shut-off and you feel that it could be because of an overheated engine then get in touch with a professional who will increase airflow to your engine.

After shutting the engine off

If your mower makes a popping sound after you have shut off the engine then this could be a problem with the muffler or the carburetor.

To fix it check the carburetor for any incorrect settings. Check the muffler if it is constructed wrongly. Rectifying these issues could solve the problem.

Also if you use the incorrect gasoline then this can cause the mower to backfire after it is shut off. Gasoline with alcohol will ignite differently than the one that does not contain alcohol. When the gas that contains alcohol gets ignited in the muffler then these causes backfire. In this case, switch to gas that contains low alcohol content or uses gas that does not contain alcohol at all and save yourself from the trouble.

Installing Anti-Backfire Equipment

There is special equipment that is attached to many mowers that prevent backfiring when the mower is shut down. These are called anti-after-fire solenoids. It is a great idea to install them that let you turn the engine off irrelevant of the speed and do not let the fuel shoot the muffler.

Final Thoughts

It sounds dangerous when your engine makes a popping sound. However, this is not something that you should be bothered about. Using the information provided above, you can figure out what caused the mower to backfire and then follow the recommended fix. It is however important to act fast to not cause any permanent damage to the mower.
