Ok, Just got this rebuilt Q-jet slapped on my truck last night. It's off a 76 Buick 455. It has an electric choke, where my old one didn't. Truck runs fine, idles fine and the new carb even fixed my hesitation problem. Anways, When I stuck it on the truck I didn't have any wire or anything on hand to hook up the choke. So I left it unhooked. Here's the problem/question I have....The secondaries won't open. Is this related to the electric choke not being hooked up? Or is there some other adjstment or something I need to check out? The truck drives just fine till ya mash the throttle, the transmission downshifts and your still on the primaries. Kinda gutless. I was fiddlin with it ealier and noticed that the choke pull off holds the the top plate above the secondaries closed. With the choke hooked up, will that allow that plate to open too? Basically I need to know what would cause the secondaries to not open and could this problemn be related to the electric choke not being wired. Thanks!
