Since installing a PCV system on my '51, 216 I've been tinkering with expected high idle from the planned vacuum leak. Today I started the truck after letting it set for a few days and as is habit I pulled the choke out, hit the accelerator a couple of times and it started instantantely.....as it should. Somewhere in letting it warm up a bit I realized the choke wasn't working. Pull the air cleaner and worked the choke at the carb and the linkage works, but the choke plate does not move....What!
Now, I'm running (what was) a nos Zenith O-10355 listed originally sold as a replacement carb for a 1937 ~ 1942 Chevrolet 216. Never messed with it much since it's worked great since I bought it from CarbKing. Come to find out it's got a spring controlled thermostat choke. At least that's my current guess. If there'a a problem with the spring setup, I'm not seeing it.
Anyone have any other thoughts on why the choke linkage won't actuate the choke plate? No bi-metal strip or bi-metal spring was obvious, just the little spring at the end of the choke plate rod.

Rotate the choke lever like you were pulling the choke, and observe if both ends if the spring move.
That choke coil is very small wire, perhaps it has broken.

Operator error. That's what I think is going on. The spring isn't broken, however just pulling the choke knob out won't cause the plate to move. Push the accelerator down and pull the choke knob and the choke works as expected. My guess is that all's good and it's been that way all along, I've just never tried to actuate the choke while diddling around under the hood before.

Glad you found your problem.
Many chokes, both manual and automatic, have a throttle lock-out to the choke.

Actually, I do have my Masters, if I live long enough I expect to get that PhD.
