I recently came across an old 1977 Clinton Chief 7.5 outboard. On the bottom of the carb, the bolt that hold the bowl on with the needle is stripped out. The threads on the carb itself are pretty much non existent. I've taken it to a machine shop and a few small engine shops and there is nothing they can do. I guess I'm looking for a new carb for it with no luck. Any suggestions? It's a clinton chief 7.5 k751 5101b serial 1370053 Walbro Carb lmb 194. Any information would be helpful.
