What causes a Honda mower to backfire?
A lawn mower backfires when burning fuel enters the exhaust or the engine. This happens when pockets of unspent gasoline enter the engine or exhaust system before the valves close. Backfires occur due to rapid deceleration, faulty components, and even incorrect fuel blend, among other causes.

The primary cause of a backfire is decelerating too quickly. The simple fix for this is just to lower the engine speed a bit more gradually. If you have a throttle that you use to reduce speed, gradually let it up instead of letting it rebound quickly.
Why does my ATV backfire when I take it off the road?
When you don’t ride your ATV for a long time, the fuel inside its tank starts to degrade. As soon as you get back on the road, the degraded fuel clogs up your carburettor. This leads to a reduction of fresh air intake into the engine, which affects the fuel/ air ratio in the combustion chamber.

Why does my ATV have so much fuel?
Yes, having an influx of fuel is often the result of air scarcity. Meaning that air flowing into your engine is getting chocked off somewhere. Many a time, it’s at the air filter. So if your ATV keeps backfiring, first check the air filter. If it’s full of deposits and large sediments, replace it (for paper filters) or wash it (for foam filters).
What causes an ATV engine to backfire when out of turn?
Why Does Your ATV Backfire?
