100% sure the keys not sheared off in the flywheel which would throw off the timing?
100% sure the floats not stuck in the carburetor causing it to flood?

Do a compression test and or take plug out and see if both valves are seating. I just did a vertical shaft engine and it would try to fire but would pop through carb,,pulled head and the Intake valve seat is out and holding valve open.
