Post the Briggs Model No., Type and code numbers. they should be stamped on the flywheel cover so we can see what we are dealing with. Have a good one. Geo

Could be both a valve clearance issue as well as an ignition issue. The "pop" through the exhaust indicates ignition and a "pop" through the carb indicates a problem with the intake valve clearance. OR, you may have a sheared flywheel key and this alone would explain the trouble.

I agree with puey, it sounds like a sheared flywheel key. Have a good one. Geo
