This is an extremely hard to find kerosene fuel mixer and throttle body assembly for a 3hp or 5hp Fuller Johnson throttle governed gas engine. It is part number 3K115 and is in used condition with no cracks, breaks, or repairs of any kind that I can see or know of. Both needle valves turn as they should and there is very little noticeable wear on the throttle shaft. It is for a 3hp or 5hp K engine and mounts with two holes 1 3/4 apart on center. It may fit other models or sizes as well so please measure your engine or consult your parts book to be sure. This Fuller Johnson kerosene fuel mixer assembly is quite tough to find so if you’ve been looking for one to complete a restoration or to put on the shelf with the rest of your engine parts here it is. The pictures tell the story. It would surely beat making one! I can be reached at 262 573 193 1 if you’d like to talk about it.
