Thanks for everyones thoughts on this! I think everyone is correct to some extent here, although I personally don't think I'd want to try stretching or shortening the springs in my distributor. In fact, if they looked like they'd been messed with, I'd replace them before I did anything else. I guess I'm leaning toward setting initial timing with a timing light, and then fine tuning with a vacuum gauge. I think MN hit it on the head when he said to then retard the timing from max vacuum to ease hard starting or pinging. I hope I'm paraphrasing that correctly. The question is how much to back off. If I back off to where it is easy to start, I'm pretty darn close to factory specs using a timing light. Maybe a 2 degrees advanced from spec. Thanks everyone for the discussion and thanks for the links on vacuum gauge diagnostics. Those are really helpful!
