As you can see in photos, it is a Ball & Ball. the only thing i can read on the fin is D602, I believe (the rest of the fin is broken off). The carburetor leaks when the throttle linkage is moved on it, leaking out of the front of the carb off of the linkage at the base of the carb. The person who rebuilt it is a retired car hobbyist who restores vehicles in his retirement. I had a spare carb that was left in the trunk when I received the vehicle. The carb that was on it had cracks in the body of it where the linkage came through in the back. He used parts of both to make one. Not sure how much he replaced. I can see new plugs in it. He said that both carbs were very worn, especially around where the linkage is. When I picked up a new gasket for the base of the carb, it was one for a 1950's chevrolet that was actually a match for the gasket, so my thought was that there is likely several carburetors that could be used on the engine. I was in touch with a parts company on the east coast but for a rebuilt one it was $800 and over my budget at this time. Any insight would be greatly appreciated. The vehicle belonged to my father-in-law who is now in his late 80s and in poor health. My hope was to get it running well enough to take him out in it again.
