First of all, I really don't know anything about repairing a non-working choke, but it looks like mine is not working. In the mid 60s this morning, I took a look after depressing the gas pedal once and the flap was wide open. The flap has very little range of motion when I try and move it, and it feels rusty when I move it by hand. I am not sure if there are parts missing. Take a look and tell me what you think - thanks!
I am also considering installing a manual choke. I kinda like them in these old vehicles.
