bansheejoel Posted May 13, 2008 Report Posted May 13, 2008 im at about 600-700ft with fmf pipes and mild porting with head cut .020 how much should my air screw be turned out? thanks Quote
BellicoseBanshee Posted May 13, 2008 Report Posted May 13, 2008 Turning the air screw clockwise reduces the amount of air and turning the air screw counter-clockwise increases the amount of air in the pilot system. Warm up your engine, then adjust the idle slightly higher than normal. Turn the airscrews in until they seat and then back them 1/4 turn and let the engine stabilize. Keep turning the airscrews out a 1/4 turn at a time, allowing the engine time to stabilize between changes, until the engine reaches its highest RPM. The air screws should be between 1 and 2-2.5 turns out. If the highest RPM is less than 1 turn (lean), install a larger pilot jet. If the highest RPM is more than 2-2.5 turns out (rich), install a smaller pilot. :thumbsup: Quote
