Mark 20H with conversion exhaust kit with an excellent mid section. This engine is in fair condition but appears to be nearly complete. Missing is the spark advance mechanism and has the incorrect transfer port covers. Carter model N carb, conversion exhaust and fuel pump and has matching numbers on the tag and block. The gear case is the short skeg style. In need of a full restoration, it does turn over. We can ship in two boxes or for $175 we can construct a wood crate for freight shipment. Actual shipping cost will be added to the cost.
