Carburetor/choke problems
I have a '68 F-250 Camper Special, automatic with a 390, that is doing a strange thing.....When I am coming to a stop after exiting the highway the choke on my carburetor "kicks out" when I come to a stop and almost makes me rear-end the cars in front of me. It only happens when I have been at high speeds for a while and come to a complete stop.
I can't figure out why this is happening....please help

Milehigh, you have some sort of a linkage problem. Here is what you can do:
When she is hot, kill the engine, pull the air cleaner and manually open the throttle. See if you see the problem, that is the choke shutting.
Check the hold-down fastener for the choke cable, tighten it, and check the setting. We can advise. Then try backing out the fast idle screw which connects the throttle to the choke via linkage.
Since you have a safety issue you can back the fast idle screw way back to disable fast idle until you figure out what is going on.
Don't oil any carb linkage.
