Can't get it to idle right! (Part 2)

do you have an adjustable fuel regulator? If so try to lower fuel pressure, edelbrock carbs don't like much over 5 psi and most gauges are not very accurate. Or watch down the carb at idle for fuel dripping to see if it's pushing past the needle and seat. Also that is not an accurate way to measure lift, if the cam has over .600 lift, it most likely has lots of duration, none of that works well with cast iron exhaust manifolds. Also where are you measuring manifold vacuum? Needs to be under the carb throttle blades, you said 12 inches at idle and 22 revving it up? Your vacuum should drop as you rev up the engine.
