Yep, my earlier cars had manual chokes, then they came out with the automatic choke. For you youngsters who have never had one, you normally mashed the accelerator pedal to the floor one time and let up. That set the automatic choke; closed the butterfly and in effect latched it closed. After the engine started, tapping the accelerator once released the choke. And as the engine warmed up, a heat tube from the exhaust manifold sent heat up to a spring that gradually relaxed as it warmed and continued opening the choke butterfly until it was fully open
Now that heat tube sometimes corroded and the only way to do an OEM repair was to pull the exhaust manifold. So in the late '50s we sold an after marker "choke heater" that clamped onto the exhaust manifold. Wish I could remember the brand name, but I think we sold them for $4.50 and they were a good seller and worked.
Now in 1995, I bought an old 1981 F250 Ford to use on the farm. It had obviously had the engine replaced and was a very good old truck. But after a year of so I found the automatic choke wasn't working. So I'd just pump the accelertor pedal when it was cold and start it that way pretty easily. And I think I did that for about a year until one day I decided I had time to try to fix it. I removed the air filter housing and there was my choke linkage firmly locked in place by a mud daubbers nest. Removed mud daubber nest and my automatic choke worked just fine.:laughing:
