You can easily make your own choke tube by picking up a pre-made length of brake line from Napa. They are easy to bend by hand and create the shape you want. Measure it out, then cut it to fit. The plain tube end gets pushed into the hole in the exhaust manifold. The threaded nut attaches to the choke assembly. That's it.

Don and Kevin,
Thanks for the info on how the choke is supposed to properly operate, and how to make a heat tube. I have experience and tools for making brake lines, so it should be possible to make one for this purpose.

I had a look at a 1940 110 manifold and if yours is similar, you can look for the heat riser hole as indicated by the arrows but note that there is a plate that is supposed to cover one opening that is not installed on these photos. You’ll need to be sure that yours is intact. 1939 may be somewhat different but the same idea.

Brake line itself will work but the heat-riser does not use the same flare fitting. Instead it has a compression fitting,

Don,
Thanks for the photos and the thoughts on using brake line. Shopped three auto parts stores today and ordered a Dorman choke heat tube kit that might work. No specs on tube diameter etc, but there is hope.

The Dorman kit will probably work. Keep the tube short. Many installations had an insulating sleeve around the tube. Anything used there must be made of high heat, non combustible material.

Steel tubing is sized by outside diameter and the choke tube size is 1/4" with a brass compression fitting at the carburetor end. The other end will slide inside the tube on the manifold.

This video was a big help when I swapped out my Chandler Groves carb for a replacement Carter on my '37 115C. It goes into the heat riser tube that had to be made to make it work the way it is supposed to.
