Small Engine Backfire?

Small engine backfires are actually small explosions that occur outside of the combustion chamber rather than within the combustion chamber. This is normally due to fuel burning in the engine before the intake valves are fully closed. Another cause of backfire can be if fuel leaks into the exhaust system.
