Can a backfiring on an engine cause damage?
Backfiring can cause serious damage to an engine if the problem is not quickly fixed. The problem can usually be traced to the carburetor or distributor. The carburetor delivers the air/fuel mixture to the engine, and the distributor ignites that mixture within the cylinders.

Air/Fuel Mixture Backfiring is typically caused by an air/fuel mixture that is too lean, meaning the mixture has too much oxygen in it. If the carburetor is adjusted properly and the choke is functioning, the problem may stem from the distributor.
What should I do if I have a backfiring exhaust?
The general rule of thumb is to tighten the adjustment screw (s) into the carburetor with a screwdriver while the engine is idling until the engine speed starts to increase, then loosen the screw (s) half a turn. If the fuel is contaminated with water or dirt, this too will result in a lean air/fuel mixture.
