Most of them came with a 15 degree advance cam (30 at the crank) and light springs usually all in by 12-1500.

Are you talking about stock? That's what are current one does right now and it's a nightmare. We can get it to idle "OK", 20 inches of Hg, but when get on it, no matter what we do, it craps itself. I was thinking our dist is the problem and a good place to start.
