All the parts you need to convert, mount, and fly a homelite 25 cc engine. I had a converted engine listed and decided to just sell the conversion parts. Included is  a shaved and balanced flywheel, prop adapter, 16x8 prop, engine mount plate, Enforcer muffler, velocity stack for carb, a spare carb, a trimmed back plate, spark plug, ignition coil, half moon fly wheel key, and mounting and spare bolts etc.
