Springtime has come, and the grass in your garden starts to rise more quickly than you would want. Cutting time, right? Still, the lawn mower starts then dies out of nowhere? Do you want to know what the reasons are and how to fix them quickly?
Wait no more, as it is all in the below section! Keep on reading to unveil the secret!
Reasons For Lawn Mower Starts Then Dies
Before finding out your suitable method, let’s find out the potential factors that make your lawn mower starts then dies!
Clogged Carburetor Bowl/ Dirty Carburetor
Your engine needs a constant supply of fuel to function properly. Specifically, the carburetor is in charge of creating combustion by combining gas with exactly the appropriate quantity of oxygen. The combustion will provide a constant spinning of the crankshaft required to power the mower’s engine.
If your carburetor is filthy or the carburetor bowl is blocked, it might make the lawn mower starts then dies.
Dirty Or Defective Spark Plugs
The spark plugs are an important part of the ignition system of your mower. They will not ignite if they are filthy or defective, and your mower will either not start or start and die soon.
Too Much Oil In Your Reservoir
Your lawn mower starts then dies, even your spark plugs are igniting, and the carburetor is clean? Then, the ultimate problem might be too much oil!
To be more specific, the sign of white smoke emerging from the engine indicates that there is too much oil in the system.
Your mower may be operating if a lot of smoke is pouring out, but only for a short time. The extra oil will ultimately drown the engine, causing it to die.
Lawn Mower Starts Then Dies – How To Fix It?
With A Clogged Carburetor Bowl/ Dirty Carburetor
You can use the carburetor aerosol spray cleaner if you want to solve the problem without removing the complete carburetor.
Ensure the cutter engine has cooled down before you begin cleaning. After that, remove all the parts belonging to the air filter and the carburetor’s outer includes. Restart the engine, and clean!
As you insert the cleaner, put the tip into the carburetor and start spraying, be extremely careful! The cleaner should be carried throughout the carburetor’s natural action while it’s operating. Continue to spray until you think you’ve used up all of the cleaners.
Finally, replace all other parts once you’ve completed the cleaning processes.
With Dirty Or Defective Spark Plugs
After you’ve located the spark plug in your mower, you’ll need a socket wrench of the appropriate size to remove them.
If the build-up on the spark plugs isn’t too thick, try to clean them instead; a wire brush and suitable cleanser will be fine enough for the work. However, you must also replace them as soon as possible. Removing a spark plug is a simple task that anybody can complete. In detail, simply disconnect the spark plug wire and use a spark plug socket to remove the old plug.
Measure the distance between the two electrodes using a spark plug gauge. Then, install the replacement plug and connect the spark plug lead. When installing, be careful not to overtighten!
With Too Much Oil In Your Reservoir
If you’ve overfilled your oil tank, we recommend measuring the quantity of oil in the reservoir with a dipstick before removing it and then measuring it again after draining. Subsequently, start the mower again after emptying some oil and checking to see whether you have enough. Once the mower starts up and runs without producing billowing white clouds of smoke, you’ve successfully solved the issue!
Still, if the problem appears to be more complicated, do not hesitate to contact a specialist!
Tips To Prevent Lawn Mower Starts Then Dies
Prevention is the best way to guarantee that your mower starts up and runs smoothly! Follow the list below, and you’re good to go:
- Replace the air filter regularly (annually).
- Spark plugs should be replaced every 1-2 years.

- Use a motor degreaser to maintain the engine cleanliness.
- Don’t overfill the oil reservoir, and remember to use the dipstick (advised).

Maintaining the mower regularly is the best method to keep it operating properly. In this way, you can also save time and money.
