Quadrajet help

Didn't you have a kit with instructions to guide you through this?
E4ME sticky at the top of this forum: https://www.thirdgen.org/forums/carb...e-rebuild.html Got to the exploded diagram a little more than halfway down the thread.
Left piece, Item #34, secondary lock-out lever. Goes behind the choke housing.
Middle piece, this one is a mystery to me, but I think it's part of the cold idle speed mechanism. Usually not taken off during a rebuild. See "Right piece" comments.
Right piece, that is either the choke coil lever, #42 (but doesn't look right), or the cold high idle adjustment (not normally taken apart during a rebuild). The threaded hole leads me to believe it's the high idle part.
I'll try to take a look at my carb in the near future to see if anything jumps out at me on the last two.

Re: Quadrajet help
okay, got the left one "installed" i think the right one goes just underneath the choke housing...but i can't figure out how, and the middle i still ahve no idea
haha, thanks for helping me undo screw-ups
edit: i got a diagram, but no instuctions and was lead to belive it was super easy and that i had somone who knew how to fix it if i had troubles >.<....i pretty much took it completly apart...around 90 peices lol ...well i did clean *everything* :P oh, and i looked at the diagram on the sticky before posting....just couldn't find it
edit: I'm dropping a new engine in my car tomoro (old lg4 died, found out it was majorly sludged, carbon buildup so bad it was very very hard to turn off (lol) and i *think* it spun a bearing (honestly it was in such bad shape, and so much of it i wouldn't be happy without replacing for more power i just went with a newer enigne cheaper lol) i got a 91tpi setup(305), that i'm swaping my old intake manifold and quadrajet over into so it should be plug and play right? same displacment, carb and dizzy...so computer shouldn't "need" any changes right?

The kits I've seen have a numbered diagram. The numbers are the order of disassembly. If it isn't numbered, you don't take it apart. You can almost do that with the GM diagram, but the order isn't quite right (air horn and gasket are #'s 1 & 2, the screws are #5 - go figure).

Re: Quadrajet help
MIddle one is the high idle tang.
Let me see, I took a handful of high res closeups of my q-jet before...
----------
Hmm, nothing good.
It goes on the rod thats behind the choke. The pointed part goes towards the front of the car, and the nubs are inwards.
I'll see if I can get a good picture tomorrow at home if you still need it.

The carb will work without any of the pieces you pictured installed.
In fact, my q-jets seem to go back together without that secondary lock-out lever - not quite sure why that happens. . .

Re: Quadrajet help
haha, gotta watch where you drop those small parts five7
Steeljab, in case you don't know how that works - it's just a lever to "lock out" the secondaries. Basically means you can't use the back two barrels until the engine is warm. It's a good thing if you ever let a moron drive your car, because it's really hard on the car to go WOT on a cold engine. But most people have the common sense not to do that, and would rather have that option for emergencies (buddy can't stop in time and you need to get out of the way - i'd rather have the use of my secondaries)
Fast idle tang - yea, without it you just don't have the higher RPM at cold idle. Nice to have in the long run though.
