factory setting is 2 full turns out, do this ,then fire her up, set revs about 1500 rpm, let the engine warm up , turn mixture screw clockwise until engine revs increase remember that screw postion and reverse the screw until the engine speed decreases again, turn screw again in a clockwise rotation to the MID point of the two positions then reset your tickover, jobs a good 'un.
