Carb Help

Rochester mono jet carb, on a 250, I unplug my auto choke during the summer cuz i dont need it, but now its getting cold so i plugged it back in....but the idle is really high, and i think its the vacuum, cuz, the spring on the vacuum, compresses all the way, and i even unpluged the vacuum hose, and the truck will go back to its normal idle...any ideas?
