Carter WCD Choke help

Recommended Posts

I am trying to hook up my choke stove pipe and i am having some issues finding the correct hardware. I am looking for a 3/16 flare nut with 1/2 20 female threads. Every 3/16 flare nut i can find is 3/8 24 thread. I bought a kit from old buick parts in hope it had the correct nut and it does not. Also bought a universal kit from dorman and no luck. Am i overlooking something here?? I have the 3/16 line coming the manifold all done and ready but i cant figure a way to attach it to the carb.

Its a 52 buick 263 straight eight with a Carter WCD carb.

The original thread on the WCD choke housing was 24 threads/inch. Perhaps some previous owner rethreaded yours?

My guess would be that if you wish to use that choke housing you will have to purchase a special thread tap, and machine the special thread nut. It might be less expensive, and would probably be less trouble in the long run to attempt to find a junk carb with a good choke housing on ebay.
