I changed my D2 5U to electric start and I am selling the pony motor and all associated parts that go with the pony motor start. see pics for details.
The motor runs and has 80 psi compression on each cylinder. I used it to start the D2 before I removed it so I know it works. I would plan to rebuild it if I was going to use it. Carb needs cleaned and the engine pushes allot of oil out of the oil fill so there is blowby somewhere in the engine. It has electric start. asking $500 for the whole lot. Item is located in Watkins Glen NY, I will not ship it so you will have to make arrangements to pick it up. I can be reached at 607-725-0366
