If you back the curb idle screw all the way off to where it’s not touching the linkage at all, it’s most likely an issue with the choke adjustment. The problem is that many reman carbs have the choke cover screws removed and rivets in their place. Which does yours have? Also, verify with a volt meter that you have 12 volts to the choke wire. If you don’t you’ll never get the idle speed down.

Ok, you covered a lot of ground there. So are you saying the first thing I need to do tomorrow morning is check if I am getting 12 volts to the choke wire by turning ignition to power on? And then if I am then go to adjust the choke (warm the truck first)? the choke cover has screws so then you are saying work on adjusting the choke next? So don't touch the mixture D screws?
