Lawnmower backfiring is a common problem with various causes. From a simple dirty air filter to complicated carburetor issues, troubleshooting can be tricky. But with a little patience and the right information, found here, you can fix your lawnmower backfire and get it running smoothly again.
Common Causes of Lawnmower Backfires
Backfires occur when the fuel-air mixture in the cylinder doesn’t combust properly. This can happen for several reasons. A common culprit is a dirty or faulty spark plug. A faulty ignition coil can also be the cause. Sometimes, the problem lies in a clogged fuel line or a malfunctioning carburetor. “A clean carburetor is key to a smooth-running engine,” says renowned engine expert Dr. Hans Müller in his book “The Art of Engine Repair.”

Another factor that can lead to backfires is old or low-quality gasoline. Gasoline can oxidize over time and lose its combustibility. This leads to incomplete combustion and, consequently, backfires.
Checking and Replacing the Spark Plug
The spark plug is a vital part of the ignition system. It creates the spark that ignites the fuel-air mixture. A dirty or faulty spark plug can cause backfires. Regularly check your spark plug and replace it if necessary. Checking the spark plug is often the first step in troubleshooting.
