Charlie: Thanks for the condenser info. However, that's one of the reasons I had Renner's rebuild my distributor and convert it to 12v modern points and condenser. Those B parts were really getting hard to find. And I did check with AAA a while back, but because I was transferring a title from my long-deceased father, they said it was too complex for them.
Step-down: You said, "I've used MMO in oil and gas , double ,maybe triple the normal amount." How much is the normal amount? I also saw Sea Foam at Auto Zone. The guy there said to also use it in gas and/or oil. He swore by it, but of course he's selling it. Is it similar to MMO?
Bob C: I'm printing out that Vehicle Code info and taking it with me. New appointment is next Friday--that's the soonest available! Sooo slowww and under staffed here. I really hope the clerk accepts this info. Seems like they could quickly look it up and verify it online.
Did you thoroughly clean out the fuel tank after it sat all those years? When gasoline evaporates, it leaves behind a varnish-like residue. Merely adding fresh gas will gradually dissolve this gunk, allowing it to get to the engine but it doesn't burn. Instead, it coats the exhaust valve stems with a very sticky residue. So an engine that ran great when first resurrected begins to miss more and more. This might be your problem.
