I agree with everyone on this one. Open the low end to about 2-2/12 turns. Fire the engine up and pop the throttle quickly to full to make sure you have a good transition. Lean the low end 1/8 of a turn and pop the throttle again. Do this until you loose a good transition and then back it off (rich) 1/8 turn. Check your high needle by taching the engine at max rpm and back it off a few hundred rpm. You just have to play with the needles a little.
