I had one that made a knocking noise due to wear in the clutch shaft bushings. That resulted in excess clearance between the clutch basket gear and crankshaft gear. It made a kind of a clattering noise under a light throttle which sounded a lot like piston slap but wasn't.

i pulled the basket off and found the my kick gear was all chowed up im wondering if the motor running and the idle gear running across a lunched gear has something to do with it i grabbed the shaft for clutch basket and there  no play idk makes no sense i pulled plug and took a drill with a socket and spun the motor by flywheel with clutch basket off and didnt hear a peep from it
