Carb tuning question. I have a 98 MXZ 500 I have completely cleaned the carbs and all the parts in an industrial cleaning system. To say the parts are clean would be an understatement. I have replaced the jets with what is supposed to be in them (330 pto side, 300 mag side) I also replaced the pilots per Ski Doo. Can someone tell me what the fuel / air screw is to be set at from snug bottomed?
