Vacuum advance: Are you running ported vacuum, from the carb, or are you running manifold vacuum? It should be manifold vacuum. If not, there's a problem.
Are the throttle blades drilled? If not, then start small. If so, open them up a little. Either way, you have to remove the carb. This will get you some adjustment back, but you'll have to re-adjust your idle mixture screws.
Does your intake manifold have a divided plenum? If so, are you using a 4-hole carb gasket? If not, get one.
Also, FYI, any cam that has any idle noticeable as not being stock is a wild cam, not a mild cam.
