I have a Zenith carb, a starter, Motorola alternator, reversing gear, and reduction drive. for sale. All have been sitting for 10 years. I removed them an A4 I bought out of a Ranger I believe. My Irwin didn't have a reduction gear. As I clean up I have found more parts. I'm adding a complete flame arrestor assembly, the 1/8" scavenge tube for the carb, a distributor with 2 point plates a water pump, an ignition coil and bracket, a Bendix electric fuel pump, a partial carb O/H kit with a needle and seat and a couple of jets.
