A very common issue with one that age is the woodruff key that keeps the flywheel aligned to the crankshaft for timing is stripped. It a a couple dollar fix, just pull the flywheel and inspect the key to see if it is chopped in half or missing.

Other than that, my suggestion is that you do a valve adjustment, disassemble and clean the carburetor, and check the cam chain tension.

No compression and backfiring is usually the Woodruff key, though.

Stick some rope down the spark plug hole to stop the piston.
