Backfiring.
If it is backfiring only when you kill the engine, allow the engine to idle a few minutes before you kill it. If it is backfiring while in use, check the intake gasket and bolts for wear or looseness.
Could be a hole or leak at one of the joints or cylinder head bolts / nuts.
carb or timing
Backfiring is usually an indication of a lean condition. When it does it during cranking, it's probably timing related.
The year, make and model info would be helpful but a large vacuum leak could do that.
Spark plug wires crossed, Bad distributor cap and /or rotor, Exhaust leaks close to engine, Worn camshaft/lifters, Burned valve, Also need to know if it is backfiring out the tail pipe or out the carburetor, it makes a difference.
You either removed the catalytic converter or you are running too rich.
if the engine is backfiring it will damage the maf,.
I have a problem. I just bought a used 1995 Kawasaki 220 Bayou. The engine started running a little rough at first. Kept getting worse and then started backfiring through the exhaust. I had the carbeurator rebuilt but still runs rough and backfires. Cranks good and idles good. What could be my problem? Thanks
Hey John==Without knowing what you have, it is strictly guessing. Check the firing order. Make sure the compression is ok on the engine. GoodluckJoe
