What causes a Honda mower to backfire?

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.
