5 hp B&S when you pull the rope to start it will yank the rope out of your hand and not start?
It kicks back so hard I use 2 hands .

Sounds like the flywheel key is sheared. Need to remove the flywheel and check. In the future please do not post the same problem twice, just gets confusing to everyone.

Sorry new here did not know I had posted twice. The flywheel key was what I checked. It is OK. Is the cam or crank gear keyed? never had one apart before. Thanks

If it's an overhead valve engine, check your valve lash.

Not to be a smart A, but are you sure the key is not sheared. Are both key grooves perfectly lined up. If the key is not sheared, you are going to have to pull the side cover and check the timing marks on both the crankshaft and camshaft. If you need two hands to pull the engine over, either the valve timing or ignition timing is off. Easier to pull the flywheel and check the key, than pull the side cover.

And loosen the muffler bolts.
If something has crawled in there & plugged the exhaust totally you get a similar result.

Yes I know the flywheel key is not sheared. I have that part off. Rivets How should the marks on the other gears line up. Are they like car cam and crank with a chain. Punched marks??
Thanks

How about giving the make and model numbers of the engine and I’ll find you a manual.
