Thanks very much for the article. I'll make the switch. My initial timing is set a 12 BTDC. Should I adjust that?  The little details do add up.

Jimmy V.

Your 12* initial (with VAC disconnected and plugged) should be fine, as long as your total timing (initial plus centrifugal, VAC disconnected) doesn't exceed 36*. Full manifold vacuum will bring your idle timing (initial plus vacuum advance) to about 27*. Your centrifugal curve should be set up tol be "all in" by about 2800 - that's a good baseline to work from for a normally-driven street engine.

Thanks again John, have made the switch and have run in place; Haven't been able to drive it yet, but am anxious to. (have other issues
I'm still working on) It may be my imagination, but it seemed to fire almost instantaneously, unlike before. It actually surprised me a bit how quickly it started, but I know I like it!!
