79 250 inline 6 carb help

Hey, I put a rebuilt carb on my 250 and now, i'm having a hell of a time with it. In order to have the truck at a decent idle, i've got to have the fuel mixture very rich, which is of course giving me terrible gas mileage, when i adjust it so it is more lean, the truck stalls. The idle screw doesn't do a thing when i turn it, i can drive it all the way in and the truck still runs?? Is this carb garbage???

put a vacuum gauge on it and see what you get. You SHOULD get about 18. If its lower than that then you probably missed a vacuum hose. Do you hear a loud hiss?
