You may be wondering Why is My Lawnmower Sputtering- in short, it’s likely due to a problem with the engine. The most common cause of engine problems is a dirty or fouled spark plug. A spark plug that is covered in oil or debris can prevent the spark from igniting the fuel properly, causing the engine to sputter.
At the same time, the other causes of engine sputtering include low levels of oil, old gas, and a clogged air filter. However, let’s see a bit more details and how to identify as well as fix the problem.

Why is My Lawnmower Sputtering – Cause & Solution
If your lawnmower is sputtering, it could be due to a number of different factors. The most common reason for a lawnmower to sputter is that the gas tank is empty. If you forgot to fill up your gas tank before starting your lawnmower, it will eventually run out of gas and start sputtering.
Another possible reason for a lawnmower to sputter is that the spark plug isn’t working properly. A dirty or faulty spark plug can prevent the engine from igniting the fuel properly, causing the engine to misfire and sputter.
Eventually, a clogged air filter can also cause a lawnmower to sputter. An air filter prevents debris and dust from entering the engine, but if it becomes clogged, it can restrict airflow and cause the engine to run rough. If your lawnmower is sputtering, check the gas tank first to see if it needs more fuel.
If that doesn’t fix the problem, then take a look at the spark plug and see if it needs cleaning or replacing. Also, check the air filter to see if it’s dirty or blocked.
Lawn Mower Acts Like It Is Running Out of Gas
If your lawn mower acts like it is running out of gas, there are a few things you can do to troubleshoot the problem. First, check the gas tank to see if it needs to be refilled. If the tank is full, then the problem may be with the carburetor or fuel line.
To clean the carburetor, remove the air filter and use a carburetor cleaner to spray into the opening. Next, check the fuel line to make sure there is no blockage. If there is a blockage, replace the fuel line. Ultimately, if none of these solutions work, take your lawn mower to a professional for further diagnosis and repairs.
Lawn Mower Sputtering And Backfiring
If your lawn mower is sputtering and backfiring, there are a few possible causes. First, check the spark plug to see if it needs to be replaced. If the spark plug looks clean and new, then the problem may be with the gas.
Old or dirty gas can cause your lawn mower to sputter and backfire. Try adding fresh gas to see if that solves the problem. If your lawn mower is still sputtering and backfiring, the carburetor might need to be cleaned or adjusted.
You can try cleaning the carburetor yourself, but if you’re not familiar with this type of repair, it’s best to take it to a professional. With a little troubleshooting, you should be able to get your lawn mower running smoothly again in no time.
Briggs And Stratton Lawn Mower Sputtering

Lawn Mower Smokes And Sputters
If your lawn mower is smoking and sputtering, there are a few possible causes. The most common cause is that the air filter is dirty. A dirty air filter restricts airflow to the engine, causing it to overheat and produce smoke.

Lawn Mower Sputters But Won’t Start

Next, check the air filter to see if it’s clogged. A clogged air filter can restrict airflow and cause the engine to sputter. Clean or replace the air filter if necessary.
Besides, check the spark plug to see if it needs to be replaced. A worn-out spark plug can prevent the engine from starting. Replacing the spark plug should fix the problem and get your lawn mower running smoothly again.

How Do I Fix My Lawn Mower from Sputtering?
If your lawn mower is sputtering, it’s likely due to a problem with the engine. The most common cause of sputtering is a dirty or clogged air filter. A dirty air filter will restrict the flow of air to the engine, causing it to run lean and eventually stall.
To clean or replace your air filter, first, consult your lawn mower’s owner’s manual. Many lawnmowers have a paper filter that can be cleaned with soap and water. If the filter is excessively dirty, you may need to replace it.
Some lawnmowers have an oil-coated foam air filter that can be cleaned with compressed air. Another common cause of sputtering is bad gas. Over time, gas can go bad and cause problems with your engine.
To avoid this, always use fresh gas and add a fuel stabilizer if you’re going to be storing your lawn mower for more than 30 days. If you’ve checked the air filter and gas and your lawn mower is still sputtering, there could be an issue with the spark plug. A fouled or damaged spark plug will prevent the engine from starting or running properly.
Consult your owner’s manual for instructions on how to clean or replace the spark plug.
Why is My Lawn Mower Not Running Smoothly?
Your lawn mower may not be running smoothly for a variety of reasons. The most common reason is that the blade is dull or damaged and needs to be replaced. Another possible reason is that the engine is not getting enough oil, which can cause it to run roughly.
If your lawn mower has been sitting for a while, the fuel may have gone bad and needs to be drained and replaced. Finally, make sure all the spark plugs are in good working order – if one is faulty it can cause the engine to misfire and run roughly.
Why Does My Mower Sound Like Its Chugging?
If your lawn mower sounds like it’s chugging, there are a few possible explanations. First, check the oil level in the engine. If it’s low, add more oil and see if that solves the problem.
If the oil level is fine, then the issue could be with the spark plug or air filter. Both of these components are essential for keeping your lawn mower running smoothly, so if they’re not working properly, it can definitely affect how your lawn mower sounds. Another possibility is that something is blocking the blades from rotating freely.
This could be anything from tall grass to a small pebble – if something is preventing the blades from moving as they should, it will definitely impact how your lawn mower sounds. To fix this problem, simply remove whatever is blocking the blades and try starting up your lawn mower again.
If you’ve checked all of these things and your lawn mower still sounds like it’s chugging, then it’s time to take it to a professional for a tune-up. Lawnmowers are complex machines and sometimes only a trained technician will be able to diagnose and fix the problem.
Why is My Mower Sputtering And Backfiring?
If your mower is sputtering and backfiring, it’s likely due to a problem with the carburetor. The carburetor is responsible for mixing air and fuel in the proper ratio for combustion. If the mixture is too rich or too lean, it can cause problems like sputtering and backfiring.
There are a few things that can cause a carburetor to mix the air and fuel improperly. One possibility is that the float level is set too high, which can cause an overly rich mixture. Another possibility is that the jets are clogged, which will also result in an overly rich mixture.
Or, the problem could be that the idle speed is set too low, resulting in an overly lean mixture.
If your mower’s carburetor needs adjustment, it’s best to take it to a professional mechanic or small engine repair shop. They’ll be able to properly diagnose the problem and make any necessary adjustments.
Finale Words
In response t Why is My Lawnmower Sputtering it is said the most common reason is that the fuel mix is too rich or too lean. This can happen if you accidentally put too much oil in the gas tank when filling it up.
Another possibility is that the spark plug isn’t firing properly. This can be due to a build-up of debris on the plug or a problem with the ignition system.
If your lawnmower has been sitting for a while, there might also be some old gas in the tank that needs to be drained out. Whatever the cause, troubleshooting a sputtering lawnmower is usually a fairly simple process.
