    Welcome aboard, Realfire!

    Any significant amount of fuel left in the tank will leave a gooey residue. I'm sure that's not helping matters any.

    How much does he want?

    You can always pop the valve cover off and look at the camshafts. That's the part most likely to rust.

    Don't get mad at us, dude! You don't even know what year 'Ski you have--and it makes a difference. It's about 25 years old and somebody may have swapped engines.

    I don't think anybody would really know, but I doubt that you've caused any damage. Giving it a fogging oil chaser ought to clean it right up.

    If it sputters on acceleration, it's rich. If it runs smooth, but just dies, it's lean.

    The low speed screws have the most effect on acceleration.

    What condition are the cylinders in? Were they original (nikasil plated) or aftermarket (liners). Others may disagree, but I'm a proponent of OEM.

    Use OEM carbs parts, too!

    Most likely it is the pump. Water gets between the liner and housing and causes corrosion, which swells and forces the liner into the impeller.

    Time to pull the pump off.

    I don't know for sure, but I believe that they changed the end fitting from aluminum to brass, or something like that.
