    2-strokes are supposed to smoke while idling. I don't know what carbs they use on that engine, so I can't tell you which is the low speed screw. You should make your adjustments in small increments, about 1/8 - 1/16 turn at a time.

    You might try running a different oil. Synthetics usually smoke less than petroleum-based oils.

    What oil and oil ratio are you using? How long has that oil been mixed in the ski for? How long have the plugs been in that engine? Is the air cleaner clean? Just to start.
