Anyone Using a Factory or Add-on Manual Choke?

A properly working automatic choke can be kicked off fast idle at any time. A couple seconds after the engine starts. The choke going closed moves the fast idle cam and gravity kicks it off when you tap the gas pedal. The fast idle cam must be clean and move freely.

In this app, isnt the choke linkage pulled up by the choke shaft? If you blip the throttle 10 seconds after you start it automatically choked, (link bar up and raised cam under throttle stop screw) the heater or heat stove isnt going to heat the spring enough to pull the choke open and off the linked fast idle cam? It will drop after the heater has acted on the spring and the throttle stop is not holding it there but only if the heater has worked on the spring and the choke shaft has been pulled clockwise into this position, then gravity will allow the free linkage to drop. Im not in a climate that demands a cold weather choke but how long do they take to heat up and expand the choke spring?
