Carburetor. In really clean shape. The only issue with this is the float bowl needs the hanger soldered or braised back onto it. It is very clean. I checked the float by submerging it in water. No bubbles or leaks. Will need gasket too. Choke and throttle butterflies work smoothly. in good shape free of cracks. Should be a good replacement This is off of ww2 APU engine Andover Motors Corp Auxiliary 2 cylinder Engine. It's in good original condition. 

Sold as is no returns
