please can any one tell me how many turns it is for an air mixture screw on a px150cc

find out what it likes, all motors will differ a little even standard ones, id set it to say 1 1/2 turns out and start it up, let it warm up and set the tickover 1000-1500 rpm or something its happy at, now turn the mixture/air screw 1/8 of a turn in or out till the tickover is at its highest, set the tickover back to where you want it and repeat with the mixture/air screw, redo the tickover and you are done, make sure it revs up cleanly and tickover is even, away you go, if you find you need to go in further than 1/2 turn out or out further than 3 turns then it suggests the pilot be changed, but as your running standard hassle geting a good idle or it bogging could be something else like an air leak
