How can I troubleshoot my lawn mower engine?

Answer by  JimmyMace (74)

This sounds like a problem with the governor - a device that helps regulate the speed of the motor. Many times it can be traced to a faulty or missing spring which holds the governor in place. This can be fixed yourself by replacing the spring, or a small engine repair shop should be able to do it for $5-$10.

Perform all your routine maintenance on the engine, such as oil changes, etc. Then, go in and check your throttle control wire.

Start by cleaning the air filter. Check the spark plug and replace, if necessary. If this does not solve the problem clean the carburetor thoroughly with carburetor cleaner.
