You may have trouble running your lawn mower if your air filter is plugged, your fuel tank is full of water, your fuel lines are damaged, your spark plug has failed, your gas cap is damaged, the deck is plugged, the choke is set incorrectly, or you are driving too fast.
You should follow the operator’s manual safety guidelines. When you work on your mower, make sure all moving parts have stopped and all spark plug wires have been removed.

Approximately 30 days after purchase, gas left in your mower or fuel can will break down and lose its combustible properties. Gasoline usually contains ethanol, an alternative fuel added to make it greener.
Alcohol naturally attracts moisture. A gummy solution forms, causing fuel system restrictions. Fuel restrictions and combustible properties can cause your lawn mower to be rough.
The fuel system can also be impacted by water in the fuel system, which causes poor performance. It can happen if the mower is left outdoors in heavy rain.
There was a little boy who put a garden hose in the fuel tank to help his grandpa. In this case, the boy unknowingly used a fuel pump hose instead of a garden hose.
A sputtering event occurs when water and gas enter an engine because water isn’t combustible and it’s difficult to compress.
The fuel tank drains a siphon. Put the right fuel in it. Sea Foam Motor Treatment stabilizes fuel that cannot be consumed within 30 days. Get more information about sea foam and its effects.
A dirty or malfunctioning spark plug
The spark plug can become dirty and covered with carbon or oil, leading to intermittent running problems.
You should replace a spark plug if the tip is too dark, if the porcelain is cracked or if the electrode is burned. Make sure your spark plug gap is correct and your spark plug wire is attached securely to prevent problems starting your mower.
Solution: Replace the spark plug with a brand-new one. My favorite way of ensuring your lawn mower runs well is to use a brand-new spark plug instead of cleaning it.
Using a wire brush, you can clean dirty plugs.

Air leaks from the carburetor
Gaskets are used to seal carburetor tormentors onto engines. If they fail, the combustion chamber can draw more air. As you probably already know, this causes a surging lawn mower engine and changes the mix ratio.
First, make sure the carburetor is securely fastened to the engine. Spray the engine starter onto the gaskets and listen for a change in surging during a running engine. Spraying the starter spray on the engine will replace the air being sucked in with combustible material
GASOHOL CLEANING
Dirt and moisture sneak past the gas filter and into the bowl, and often this will solve your problem. However, if grit has entered the jet, you’ll need to strip down and clean the carburetor.
Here is the price of the WD40 carb cleaner on Amazon. WD gets into all the tiny passages and breaks down varnish deposits.
Clean the fuel bowl with these tips. The bolt that holds it on is sometimes a crucial part of the fuel feed system. If the gas is older than three months, cleaning the bowl will not help. Drain the tank and carburetor bowl, and fill it with fresh gas.
If this works for you, great job! Sorry, I wrote a simple guide to help you – “Carburetor cleaning”.
The gas cap should be vented
Improper venting of the gas cap increases vapor lock risks.
Fix: Remove the cap and check if the vent hole is open. Alternatively, try cleaning it. Test again with some air. If it can’t be cleaned, replace it.
