I am tending to agree with you on more initial. It definitely is stubbling below 3000 rpm. Much more sensitive to the cam/intake setup which make power at 3200 and up. Even putting in smaller jets, two numbers or 9% reduction, didn't help, in fact made the low speed bog worse.

Actually the new Crane unit allows for optically changing the initial on vac advance. Guess I will just bite the bullet. You are right about the FMS setup, simple but it does present some challenges.

You are right about following the carb builder, I started this thread to get some educated opinions. The changes are on me since he built the carb not the combo. I do have faith in him, especially when I get the cam on at 3000 the thing screams. Local police just seem to dislike it when I shake the neighbor up.

I do appreciate all of the opinions/suggestions.
