I bought a couple of carbs at a swap meet and the guy threw in a third one just to get rid of it. It is just the main body and the air horn, no base plate. I took the air horn off and found out that it had a set of DA rods and a "S"hanger on the secondary . I am curious; what was the application for this carb? It was manufactured by Carter. The number is 4954S. Under that is J4. Front fuel inlet. Any help with identification would be appreciated. Billy2
