there is 2 screws you can play with on the tm38 mach z carbs, i know one is for the pilot mixture, but what is the other one for, and witch is witch, i guess the pilot one must be the one underneath the carbs because the ones on the sides on mine are like 6 turns out and i have 50 pilots and it has a idle hang, anybody 
thanks guys
thanks guys
when the screws are in front of the slide(engine side) they are fuel screws, if the screw is behind the slide its an air screw, so the air screw on the intake(airbox) side of the carb works the opposite from the fuel screw, out is lean, in is richer, if your having idle hang the screw needs to go in. I would try .25 turns out from lightly seated
