Can't get idle down ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just bought a 72 4x4 with a 350 and a Quadrajet carb. This truck had been sitting for quite a while. After I got it I replaced the gas tank and rebuilt the carb . Since I rebuilt the carb I can't adjust the idle down, its high like 2000 rpm plus. I can pull the throttle foreward and get it lower but it will not adjust any lower, feels like something is holding the linkage back. Any ideas, I have not taken the carb back apart yet. thanks
