    Bob, I received my 3.3 Sportwin as a basket of parts with the pistons out.
    After many queries, study of literature, etc., I installed the pistons, but
    still didn’t feel 100% certain there were in correct. The longest I ever got
    it to run was about 30 seconds, then went downhill from there.
    I then queried different owners to see if their piston’s 90 deg. step
    was on the port or starboard side as they looked in, or probed in the
    spark plug hole. Of course I got two different answers! Galerider was
    recently the "third", and deciding vote. "Steep step" on the port side.
    So if yours isn’t the same, one of us still has problems, ha, ha.
    I determined from Galerider that my pistons are in correct.
    Think I’ll re-visit the low speed adjustment on the carb and make sure the
    air shutter is in the correct position for starting.
    Good Luck, Buccaneer
