    "Yes, I would suspect 1) old fuel 2) too much oil in the mix or even 3) motor had been stored - fogging in the cylinders.

    New gas, 50:1 with a quality TCW-3 rated marine oil and take her out for a good run - clean all the cooties out and see if she still smokes.

    Smoking on a 2 stroke is not indicative of a problem the way it is on a 4 stroke.....

    If a 4 stroke smokes you have a problem, if a two stroke smokes you usually have too much oil in the gas...."

    "Ok, that sounds like a jet issue (low speed) in the carbs. Could simply be an adjustment but this motor is pushing 20 years old and removal/disassembly/cleaning and at least gasket kits if not rebuild kits would probably be in order...."
