I have a 1970's Cushman Trackster that needs a new engine. The original OMC engines for these things was a horrible design and parts are almost completely unavailable.
I came across an air cooled Polaris 440 Sport at the junk yard that appears to have an intact engine and electrical system. I have access to a well equipped machine shop and will be making the tapered adapter shaft to go from the engine to the transmission setup in the Trackster. Problem is, the engine rotation is backwards.
So...what's involved in getting a 440 twin to run backwards as far as the ignition system goes? I won't be able to use the oil injection system unfortunately...or, I'd have to figure out how to run the transmission off the fan side of the engine...which has possibilities.
