This is an original fork style fuel mixer and check valve assembly for a Monitor VJ pumping hit and miss gas engine. It may fit other models so please do your homework to be sure it fits your application. It is in used condition with no cracks, breaks, or repairs of any kind but will need a fuel needle (available from several vendors) and some cleaning before it’s ready to go to work for you. If yours is broken, missing, or repaired here’s a chance at a much nicer one. It would also make a great spare on the shelf. The pictures tell the story. It would surely beat making one or trying to repair yours! I can be reached at 262 573 193 1 if you’d like to talk about it.
