It may be a result of many things, and finding the principal cause is critical for effective prevention.
Common Causes of Small Engine Backfires
Ignition Timing
Firstly, the wrong ignition is one of the foremost reasons why small engines backfire. Secondly, if the timing is off, the combination of air and fuel may want to catch the heart at the wrong time, which would be known as a backfire.
