Specifically for a 2HP throttle governing Witte engine. Make sure your engine is the screw in type style and is 1 1/4 before purchasing!! This carb seems to be in pretty decent condition considering it’s age. However there is a fuel adjustment valve that is broken off and stuck!!!! The throttle shaft moves freely and the butterfly seems to close up against the housing like it should. Probably doesn’t seal off the air 100% but Shouldn’t have to with a throttle governed engine. The throttle adjustment knob is rusted stuck, shouldn’t take a whole a lot to work it loose though. See pictures for the absolute best description and keep in mind this is a used part that is almost 100 years old!
