So all of the carb adjustments I've done to date have been with all of the vacuum lines capped. I can get the car where I want it, idle at 850-900 in park, timing at 16*. All good and well. But if I hook up the dizzy to manifold vacuum, timing jumps up to close to 30, and the RMPS jump up to 1200. That's still in park at idle. I expected a slight increase in timing and rpms. but very slight. I don't even make that much vacuum. The dizzy is a Mallory Unilite, that I will be swapping out for the Duraspark soon anyway, but doesn't this sound like way too much advance at idle??
