This is an extremely hard to find original fuel mixer or carburetor for a Fairbanks Morse Jack Jr, 1hp Type H hit and miss gas engine. It is part number 15JE6 and is in used condition with no cracks, breaks, or repairs of any kind that I can see or know of except the mounting holes have been enlarged which really shouldn’t be seen after it’s mounted. The mounting holes are 2 1/4 inches apart on center. The fuel needle moves as it should. 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 and may be homemade but with a little adjustment should be effective. This Fairbanks Morse Jack Jr 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.
