Question about 1985 Ford Bronco II
Been having fuel issues with my truck and replace the mechanical fuel pump on the block. Fired it up and ran smooth, went down the road like a mile, and it died, started looking around my carb and noticed the choke plate was sitting straight up. after looking around for a while I got stumped, this is my first vehicle I've had to work on with a carb, so I don't know a whole lot about it. I assume I need a spring to keep the plate closed but i'm not sure, any help would be great
The choke butterfly (choke plate as you call it) can only be partially closed when the engine is cold. It is used to create a low pressure under in the throat of the carby which causes excess fuel into the engine when cranking and early running to help warm up and to prevent the carby icing up. After a few minutes the butterfly will be fully open and remain that way while the engine is at operating temp. As to the engine stopping down the road look for another fault -- Like incorrect fuel cap on tank , blocked fuel filter, dirty air filter If the engine starts easily and runs I doubt that the fault will be in the carby.

Does your "wait to start light come on"? If not check fuse#22 under the hood. If it is blown it is most likely your fuel heater inside fuel canister. Unplug the wire on drivers side of fuel canister, replace the 30 amp fuse and try to start. I hope that helps!
