Mr Beerman,
My 1979 Cadillac pinged like crazy on regular gas & needed to run premium grade fuel. That car has vacuum hoses everywhere. I replaced every hose on it & it ran like new on regular fuel & NO pinging!
I also have a 1958 Johnson 18 that was stumbling. Replaced the top seal & oil line to top bearing & cleaned up the mag & contact areas. Never had a bump or wet powerhead ever again. Please do not give up & sell it. Replace the shift shaft seal, top crank seal & oil lines. It will purr for you. If not get a spray bottle of premix & run it at idle. Spray a little fuel on the crankcase halfes & if it speeds up it is leaking.
ATTACK it like a new motor for your collection. It will run very nice, I know you know how to get it right!!!
