Anyone have a pic of a 2bbl carb linkage setup?

I rebuilt my Rochester 2GV carb tonight and trying to figure out if I have the fast idle cam linkage setup right. It looks right but when I pull the throttle back, it falls closed and when full throttle (off the car) the throttle bracket will move it open just a bit. I don't know if I need to have the carb on the car or if I have it hooked up wrong. If someone has a pic I'd appreciate it. I'll grab a picture of mine tomorrow. Also, someone took out the internal filter but left the spring in there, I don't think it needs to be in there anymore, what do you guys think?

Give me an hour and I will snap pictures of my setup for you. I have the same carb sitting on top of 350. The only thing is that I have replaced the snorkel type air cleaner with open one so all the vacuum lines are gone.

If you need any other pictures/angles let me know. I am going to the car show right now but should be back before it gets dark.

The black wire with silver tape is from cruise control that's disconnected.

Thanks for the pics! Do you think you could snap a pic of the fast idle cam bracket on the throttle? In picture 3 it's the piece that the back rod (furthest to the right in the pic, closest to the firewall in the engine bay) runs down to. It connects from the top of teh carb down to a little bracket deal on the throttle linkage. Mine's a little different from yours, I have a side outlet for my fuel on the passenger side and my throttle stuff is hooked up a tad differently but should all work the same.

Three more pictures. It was kinda hard to take picture of this area so if this is not good enough, let me know. I still have the other carb that was originally on the car. I think it has all the linkage but obviously it is not on the car.

I've rebuilt quite a few carbs in the past- it sounds like you've got it put together right. And yes it needs to be on the car for the choke to work properly since the bi-metal choke spring on the other side is attached to the intake manifold. The weight of the fast idle cam will usually make it drop like that if the other side of the choke butterfly is not hooked to anything.

That's what I was thinking but wanted to make sure before I slapped everything back together lol. I've rebuilt holley's before and some Edelbrocks but never one of these 2-jet's. Thanks for the pics Drabina, that's how I have mine hooked up too so it should be good to go.
