Nice original head for a Aircooled fuller & Johnson vertical pumping engine. No breaks or repairs. Part numbers j3B and J62. Valves are loose, valves need cleaned up and a quick lapping would be very recommended. The mounting holes are spaced 3 1/4 apart from each other on center. Good 3/4 threads for the carb and exhaust. Please see pictures for the absolute best description. This item is old and used, it’s not new!
