Here a head for a 2-1/2hp and or a 3hp Sandwich gas engine. It is in pretty good shape. There are no cracks, breaks, or welds that I can see or know of. For questions 419 789 1159. 4 x 4′ mounting pattern. The raised center is about 4-3/16 in diameter. Just under 7-3/4 in overall diameter. 1-1/4 hole for carb. 1-1/4 pipe hole for muffler, I cleaned those threads with a tap and a pipe will screw in just fine. The valves feel good in their guides. They should probably lap in just fine but there is a possibility there will need recut just a little. There is a some gunk in the water jacket area but it should clean out just fine. No cracks, breaks, or welds I can see or know of. Very hard part to find. Heavy, weighs about 21 lbs before any box or packing material. Thanks for looking at this listing!
