Quadrajet rebuild

It's a M4MC quadrajet. I rebuilt everything on it, but now I'm having trouble getting the stuff on the choke side back together. It's electric choke.

The tang that hits the lever for secondary lockout, I see nothing that will move this tang.

I'm not sure if my fast idle stuff is working right, when I put the fast idle follower on the high step, it doesn't really hold the throttle open like I figured it would.

And my vaccum break that goes to (i guess) the choke flaps on the secondary, pushing it in and out does not move those top flaps on the secondary. Nothing will get them to move (besides moving them by hand). There is no rear vaccum break.

Anyone have any pictures? I have the shop manual for the truck, but those black and white hand drawn pictures are hard to tell, and I can't get a good enough angle on any picture I took, or any pic I found online.

Thanks.
