This is an original 7043100 Chevrolet GM 2 Jet 2 barrel Carburetor. Use it for parts or rebuild it. I have not opened it, so I do not know if it is complete or missing parts on the inside.  Looking at the outside of the carb, i do not see anything broken, cracked or chipped. The butterflies do open and close. Comes as pictured. Free shipping in the 50 United States
