This is a very nice original fuel mixer or carburetor for a 3hp Fuller Johnson hit and miss gas engine. It is part number 3NB110 and is in used condition with no cracks, breaks, or repairs of any kind that I can see or know of except for a very well done repair on a mounting ear. It is for a 3hp engine and mounts with two holes 1 7/8 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. The choker moves as it should. It needs a fuel needle which are available from a few hobby suppliers. This Fuller Johnson 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.
