I replaced my carb over the week-end, but am struggling to get the choke to work while the truck is cold. Warm-up took a few minutes before I replaced the carb. Now the time has doubled. The carb does not choke down at all when cold. It is a stock Motorcraft 2 bl on top of a stock 360. I have completely tuned it up and I do not belive I have and vacuum leaks.

ps- I've had it off since the picture and using a little-hand-grinder with a 4+1/2" flap disk on it... "cleaned up the looks some" and made that heavy-ol'2100 even lighter too ;)
pps- YMMV
If the choke spring is working, perform the adjustment when completely cold. Loosen choke cap screws and rotate choke housing until it just closes the butterfly, with just a small gap remaining. Then start, and watch that it begins to open in a reasonable time. You should also set your high speed idle when you first start. It is usually a screw opposie the choke side, up against the kickdown cam. You want it set so that the engine is not screaming when it is at high warmup idle (choke on).
If your setup has no auto kickdown actuator, you must manually kick it down. Adjust it if it takes too many presses of te pedal to kick down.
I hope this makes sense... Easier for me to do it than explain it! lol
