I made a brass carb for the tri car. In one of Rick's, {Indian22}, photos I saw a brass railing connector and that started me thinking about a carb. I purchased an antique brass carb from what was possibly a tractor but it was heavy and a bit too large.
I used 1" fittings. One was a four way T connector for the main body. The bowl is a ball that fits on the end of the brass tubing. The top is a plug that fits inside the tubing to finish it off. I purchased both a flat and domed plug. the flat plug worked best for me. I'll include a parts list and contact information for the company I bought them from.
The brass cable adjuster is something I had in the brass parts bag. If I hadn't had that I would have used a 1/4" brass gas line fitting. It doesn't need to work since the carb isn't real. Just improves the look.
I used some 1" outside diameter towel bar I had to join the T section to the ball on the bottom. J.B.Welded it after scuffing up the surfaces to provide a better grip for the epoxy. The top cap I epoxied the towel bar tubing to the inside of the T section but left the end cap loose so it can be removed so I can secure the cable inside the cap. I have a brass bolt and it will hold the end cap in place after a hole is drilled and threaded.
