Default 84 runs great cold, dies when hot?

I have an 84 f150xlt 4.9, that is very particular about the temperature it wants to run in. It runs perfect when it's cold, but will die if I let off the gas once it has warmed up. The carb has been rebuilt, the ignition control module has been replaced, just did a tune up (plugs, wires, cap, etc.) and the distributor itself has been replaced. I'm not very mechanically inclined, so some advice would greatly appreciated.

Double check the vacuum lines for one cracked/off, recheck the torque in the carburetor mount nuts. If that does nor fix the issue then adjust the warm idle screw 1/4 turn to increase idle rpm and see how that works, once you get it to idle reset your idle per the emission chart (curb idle warm)

Hope this helps
