Auto Choke problem figured out

My car has been running too rich since I bought it in October. I've rebuilt the carburettor, replaced the needle, leaned the mixture all the way, leaned the idle mixture, installed a manual choke, and still, the car runs way too rich. But I think I found the problem yesterday. (I can't believe I didn't find it sooner.)

The head of one of the three screws that attach the choke to the carburettor is broken off. I don't know why I didn't realize it when rebuilding the carb. Anyhow, the choke must not be held on tight enough (with just the two screws) because the lower part of the choke is usually damp with fuel that seeps out around the gasket. If fuel can leak out, I assume air can leak too. This has got to be the problem... I've done everything else!

The good news is that there is approximately 1/2 inch of the screw exposed so I should be able to remove it with some visegrips. Now all I have to do is find a replacement. I guess I need a new gasket too.

I hope this solves the problem. Spring is just around the corner and I'd like to be able to drive without producing a noxious cloud of black exhaust.
 
You might want to check out "Weimerology" on my website (https://www.theautoist.com)...he's done a great job of walking us through the auto choke on a Zenith carb & there's a link to a super site on rebuilding that carb...
