I have a 550 fan engine with 1044 miles on it. The lower end is in good shape and is complete. Have one good cylinder and head. Have one damaged cylinder and head. Have all the engine stuff also, carbs, harness, oil pump, covers, clutches etc. Will sell for reasonable prices. will sell it all or separate. Prefer to sell the lower end local to avoid shipping hassle. All other parts can be shipped. Located in southern Maine.
