Since you said flywheel key is intact I suspect a camshaft timing issue as I see ignition kick back. This engine has a plastic camshaft that can slip on the steel shaft.

Yes when looking up the camshaft and timing gear. The original timing gear was plastic but superceded to a metal timing gear and camshaft has plastic sleeve on the metal shaft.

Chinese or OEM?

How far do they extend into the head?
flywheel key is good,
Might double check this. Several people have told us the same thing. 7 pages later of help and we get told the OP had a bad FW key.
60 psi compression
No thing for a Briggs.
Tries to start but doesnt.
I would say you have a fuel delivery issue.
