i have a 1983 ski-doo nordik, does anybody know the proper specs for the adjustments of the air screw or should i start out lean or rich? the sled has a 377cc rotax in it for an engine....i rebuilt it last season, i took the carb apart and cleaned it because the jets were gummed up. but the thing is iam not sure what to adjust first on the carb.(its a mikunki carb, not sure of the model #)

Right now the sled wont stay going, unless the throttle is pumped and even then it still shuts off after several seconds, plus i think the fuel mixture is rich because both plugs are wet after the motor stumbles for a min( they are not fouled, both have plenty of spark and gaps are set). i need info on the carb adjustments please[?]

i rich fuel/oil mixture will not leave your plugs wet. it just smokes alot and fouls plugs.
your sure the pilot jet is clear?
have you played with the iddle screw?
