When I received my kit and checked the contents. It was discover that all the "O" rings were missing. The 3" o rings were ordered on line. When the rings arrived, the unit was assembled and work perfectly.
It went together easily and ran okay but runs much better after balancing the flywheel. To balance, I wrapped about 1 inch of wire solder around the light weight spoke.
