Given that the timing is set correctly, the air bleeds are properly sized and throttle blade position at idle is covering the correct amount of the idle transfer slots, I run them 1/2 to 3/4 of a turn out from lean mis-fire.
Screw them out just until the idle will no longer increase, then screw them back in until it starts to lean mis-fire (idle decreases) then back out 1/2 to 3/4 of a turn. Go around until they are all consistently 1/2 to 3/4 of a turn out from lean mis-fire. it may take several times to balance/stabilize them.
