First of all, are your carbs accurately balanced? I use a CarbTune II (http://www.carbtune.com/) for this purpose.

If memory serves me correct, a half decent starting point is about 4 turns out on the idle screws. Turn all of them all the way in and count the turns as you back them back out.

If you have access to a CO meter, adjust for idle around 2.5% CO. It is rich, but needs to be rich to avoid trouble at pickup.

I assume you have checked your ignition and cam timing? If not, this is absolutely the time to do so. Also check for vacuum leaks.
