Hello. I'm new to the forum and can use some help. I have a '72 GS with a 350 4 bbl Q-jet. Can anyone help me with a problem I have run into after overhauling the carb. When the throttle is set to wide open the throttle valves are only opening about 50%. Did I miss something in the reassembly? I didn't change anything externally on the carb. Linkages went back on as I removed them. I have o/h'd 2 bbl carbs before but don't remember running into this problem. Thanks in advance for any help. xprattrug
