when you put the carb on did you do a tune up on the truck? new plugs, wires cap rotor etc? if not oyu may want to try that as its recomended with a weber install, they are very hard to tune, i know mine tok a long time to dial in correctly, check all your basic stuff before you try to change the jets, the stuff i said above and check your timing as well
