This B&S 900 problem with backfiring and jerking starter rope out of hand.
With only limited "smarts" for this engine, thought timing off so looked at flywheel key and it was sheared in two. Checked valve clearance and appeared to be ok. New shear pin, reassembled but same problem.. hard to start and when it fired, backfired only. Looked and key was sheared again.
Thinking this is a camshaft issue, but don't know how to check if that is the problem without tearing the engine apart.
Any help or guidance for this beginner?
