i am patching up an engine i bought a while back to run until i can do a complete rebuild on another engine. i did new rings and gaskets and hand lapped the valves. putting things back together i found i have one stripped bolt hole in the crankshaft. replacing the crank is something i don't want to do right now. i am considering either tap out to 1/2 20 and drill the flywheel to match, or helicoil the threads back to 7/16 20. has anybody tried either of these repairs or can make suggestions?
