+1. The fuel screw should be between 1.5-2.5 turns out. If you have to turn it out more than 3 turns, go up one pilot jet size. Do you have any popping on decel? Crisp throttle response? Do you have an adjustable needle in it? What needle is in it if it is adjustable, is it the NCVQ? Do you have any bog, when you stab the throttle?
