This is an original 3-needle fuel mixer or carburetor for a 3hp International Harvester Type M gas engine. It should fit both the ignitor fired engines and the spark plug fired engines. It is a good core that should easily be rebuildable. There are no cracks, breaks, or repairs that I can see or know of except for the venturi which is always broken upon disassembly. It needs some needles and other internals which are readily available from several of the hobby suppliers. It should be a very straightforward project. If your original mixer is missing look no further! The pictures tell the story. I can be reached at 262 573 193 1 if you’d like to talk about it.
