The fitting on my Carter YF 2101S autochoke has broken off. Does anyone have any ideas how to fix this. Would JB Weld be sufficient to put a new fitting on there? Here's a pic of how it looks.

Let's try again

Broken Fitting

The easiest way of which I am aware that works would be to make a new "repair" fitting out of a piece of hex brass.

Internally thread the remains of the projection on the airhorn.

Make the repair fitting with male threads to fit the female threads you made in the airhorn, and "burr" the male thread slightly. Thread the other end of the repair fitting with the proper thread for the cap on the heat tube. Leave enough of the "hex" to hold with a thin wrench.

Now screw the repair fitting into the airhorn. The "burr" will cause the thread in the fitting to "seize" in the airhorn and stay in place.

As an insurance that it stays in place, hold the fitting with a thin wrench when installing/removing the heat tube.

I hadn't thought about putting internal threads on there. I'll have to look into that.

Finally got around to fixing this. I hope.

First a little better picture of what I was working with.

Broken threads

Now for the fix. I started with one of these

Edelmann Part # 744460

Thats a 1/8 NPT to 1/4 hose fitting. This is what I did to it to make it fit.

Modified fitting

Drill press and a file will remove material. Not the best way to do it but it's what I have access to at the moment.

Here's how it fits

Fitting in carb

To hold it in place first I used some High Strength Sleeve Retainer Napa # 765-1149 that I had left over. After it dried it held the fitting in place. To make sure I don't have a vacuum leak I used some JB Weld. Here's the finished results.
