Also Carl,
You may need to tune the idle air bleeds,but that should be done with precision.Just don't let anyone do this,as .003-.007 bigger will make a differance on the idle richness
Also,turning the air screws in leans it,Out richens it,so try to get the air screws all set the same,between 1 turn and 2 turns,If that won't cure it,I'd say the idle air bleeds need tuning
*EDIT*
