My Briggs and Stratton has had a popping problem for a while. It starts up fine and runs fine, but it always pops no matter what speed the engine is running at. I have cleaned the air filter, replaced the spark plug, cleaned the carbuerator bowl,replaced the needle valve and sprayed the carb with carb cleaner. I have to have the engine run slightly fast on idle otherwise the engine quits after a few seconds.

Is it popping out the exhaust or out of the carb?
Could be a few things.
Carb may just need a proper strip down and clean.
Also if through the carb it could be head gasket or valve but they would give symptoms of bad starting aswell.
If giving the carb a good cleaning (find someone who does ultrasonic cleaning if possible) does not help, I would suspect you have a burned or sticking exhaust valve. This will mean pulling the head to diagnosis.

Have you checked the flywheel shear key for damage?
