What would cause the choke flap(?) to stop closing ? Was working up till this AM. When I push the gas to the floor the flap stays completely open/vertical. Before it always closed as it is supposed to. Have not touched a thing .... at a loss.

Thanks

 
Either the linkage is hanging up on something or the bimetal spring housing is loose and has rotated. When you open the throttle by hand can you close the choke butterfly?

Also, make sure the throttle cable is connected to the carburetor lever.

I can close the butterfly by hand but is springs back open when I release it. Did not try this while holding the throttle open. The car is at another location might get back to it for a couple days. I will check those other suggestions ... thanks

 
If you have an electric choke, it receives voltage, and is heating, any time the key is in the "ON" position. If for some reason the key was on for even a reasonably short time, the choke will have begun to open. If you leave it on for a couple of minutes it will be wide open and won't close until the key is turned to the off position and the choke element is given time to cool to ambient temperature. Let us know what you find. Chuck

Thanks, that might be it ... let you know in a few days .... thanks !

+1, good idea Chuck. This is why the electric choke should be connected to the stator output on the alternator.

Hello,

I have a one wire alternator .. I will have to contact the company and see which of the two blade connector's on the back of the alternator is the stator output. Thanks

 
Hello, I've been looking for a place to connect my electric choke, and found this thread. I was preparing to hook the choke to the stator post on the alternator, and I may have a problem. This post has about 10.5V ... all the time ... even with the key off. Is this correct? I understood the purpose of using this connection is the choke would only have power when the car is running. Thanks.

 
Thanks. I assume this means there's a new alternator in my future. Had I not been checking sources to connect the choke, I probably would have never noticed this ... at least not until the alternator completely failed.
