An engine backfire occurs whenever the air-fuel mixture in your car combusts somewhere outside the engine's cylinders. This can cause damage to your car's exhaust or intake if left unchecked — and it also means that your car's engine isn't making as much power as it should, and is wasting lots of fuel.

What causes a lawn mower engine to backfire?

The primary reason why a lawn mower backfires is due to the fuel mix being too lean. As a result, there is a high amount of air in the fuel mix, which causes incomplete combustion. When this mix then moves to the exhaust system, the left over fuel spontaneously combusts, causing your engine to backfire.
