What causes an ATV to backfire through the carburetor?

This minor explosion takes place in the engine’s intake or exhaust and can cause the vehicle to shut off. Common reasons include issues with the fuel/air mixture, carburetor, ignition, or fuel pump.

Backfiring occurs when one (or more) spark plug in the ATV engine ignites the fuel when it’s out of turn in the chamber, and the exhaust valve on the cylinder is open. When the explosions happen elsewhere, there will be a ‘pop’ sound followed by a short interruption of the engine’s normal operations.
