When you set the choke there are many adjustments, most require linkage rod binding and a choke angle guage, also there is a cold high idle setting when the choke is on, all of these adjustments are different for each carburetor number, the carb number is stamped on the carb, there are 20 or so numbers of carbs for your truck they are called calibrations, My suggestion to you is to get the number off your carb and buy a rebuild kit made by Jiffy, they are the best and provide detailed instructions for each carb number covered by the kit.
