8 Tips for Fixing Lawn Mower Sputtering

Lawn mowers are meant to make lawn maintenance an easy task. But when your lawn mower starts sputtering, it can quickly become a frustrating chore. A lawn mower sputtering is a common problem that can have a few different causes. But don’t worry, in most cases it’s a relatively easy problem to fix.

Here are a few fixes for lawn mower sputtering you can try before taking it in for professional service.

Check the gas and oil

One of the most common causes of lawn mower sputtering is old or dirty gas. Over time, gas can start to break down and form deposits that can clog up your lawn mower’s engine. To prevent this problem, always use fresh gas and be sure to add a fuel stabilizer to your gas can. It’s also a good idea to empty your lawn mower’s gas tank at the end of the season to prevent these deposits from forming over winter.

Change the spark plug

If your lawn mower is sputtering due to a dirty spark plug, you’ll need to replace it with a new one. You can find replacement spark plugs at your local hardware store. Be sure to consult your lawn mower’s owner’s manual to find the correct spark plug for your model.

Clean the air filter

Another common cause of lawn mower sputtering is a dirty air filter. A dirty air filter can restrict air flow to the engine, causing it to run lean and eventually leading to engine damage. To clean your lawn mower’s air filter, simply remove it and wash it with soap and water. Be sure to let it dry completely before putting it back in place.

Check the blade

If your lawn mower is sputtering due to a dull blade, you’ll need to sharpen or replace it. Most lawn mowers have a detachable blade that can be removed for sharpening. If the blade is too damaged, you’ll need to replace it with a new one. You can find replacement lawn mower blades at your local hardware store.

Clean the engine

A dirty engine can also cause the lawn mower to sputter. To clean your lawn mower’s engine, you’ll need to remove the spark plug and air filter first. Once these are removed, you can use a garden hose to spray down the engine and remove any dirt or debris. Be sure to let the engine dry completely before putting the spark plug and air filter back in place.

Check for leaks

Another common cause of lawn mower sputtering is a fuel leak. Fuel leaks can occur at the carburetor, fuel line, or gas tank. Inspect your lawn mower for any wet or oily spots to check for leaks. If you find a leak, you’ll need to repair it before using your lawn mower again.

Adjust the carburetor

If your lawn mower is sputtering due to a dirty or damaged carburetor, you’ll need to clean or replace it. Carburetors can be cleaned with a carburetor cleaning kit, which can be found at your local hardware store. If the carburetor is too damaged, you’ll need to replace it with a new one.

Take it to a professional

If you’ve tried all of these fixes and your lawn mower is still sputtering, it’s time to take it in for professional service. A qualified lawn mower repair technician will be able to diagnose and fix the problem quickly and get your lawn mower running like new again.
