just rebuilt runs bad

I agree with stabbing a different distributor, Especially after you saying it runs good with 60 degrees of advance. I have had that happen before, Backfires no power idled like crap, Retimed still crap twisted the distributor all over to find it idled and revved clean with TONS of advance. I replaced the distributor with a known good one and fixed it, EASY place to start and rule out your electronics I would be surprised if this wasn't it.

Good luck,
Joe
