rebuilt my Q-jet need some direction..

[ejones]

I had my Q-jet for my 83 Sierra (305) rebuilt because I was told it needed it and I believe it did. My truck started backfiring and running like crap, to start it I would have to pump and pump the pedal while cranking to get it to start (still do after carb rebuild) I notice that the secondaries wouldn't open before I had the carb rebuilt. If I wedged the secondary open it would run "ok". I want to take it to a shop to get the truck dialed in correctly but at this point i would need to tow it there. I need some direction to get it to run ok enough to idle and run so I can drive it to a shop.  I haven't adjusted anything yet but I'm wondering if the ported vacuum switch or vacuum canister could cause this type of issue?

I did some research today via youtube and made a couple observations one being it doesn't look like my choke closes far enough but turning the assembly doesn't accomplish it getting closed enough. @ being the base idle screw wasn't even in contact with the throttle so I turned it in. It would run (barley) with the screw in until it warmed up then it wouldn't idle at all as it did before. I wanted to adjust the idle mixture screws but they have some weird type heads? where can I get a tool to use for these "reverse straight edge" screws? I've never seen these before

Most parts stores sell a flexible driver tool that has the end you need. The secondaries will only open under demand, so don't expect them to be opening at idle. Run the idle mixture screws all the way in and then back them out equally, maybe 3 turns out or so to begin with and see if it runs. Make sure you don't have any vacuum leaks and everything is hooked up. What kind of choke do you have?

It's an electric choke. I plan to buy the tool and also get new plugs and wires so I can rule out a bag plug/wire while I'm at it.
