The way I understand it is that the choke is used for cold start and the throttle cable is for cold running. I believe the operators manual actually recommends doing it that way.
Also, not sure how accurate this is but I've heard that on the farm the throttle cable was used when one man was driving and grabbing hay bails. Put the truck in gear, set the speed to a slow crawl and steer from the running board while jumping off to toss bails in the bed.
Seems like a good way to wreck your truck tho.
