Reassembling the carburetors on the rail and hit a snag

Its the carbs that came on the 77 cb750 k7 . I can not for the life of me find any literature or pictures of where the springs go that belong on the choke rail or so I assume. One is a really thin loosely coiled spring in the shape of an O with the clips next to each other on the top. One clip is straight and the other hooked out to the side when viewing it from the top. The other is a typical spring (very small) with the hooks facing the same direction. It kinda looks like (__iiiiiii__) . Sorry for the descriptions and yes I was not very smart to have not taken pictures before disassembling. Any help would be greatly appreciated!

I can't tell you which goes where from where I'm at right now, but I can get you any pictures you might need of a fully assembled set of PD42 carbs (keyhole ones) later on if ya want? I believe those are the ones you habe?
 
Keyhole sounds right because the top of the carb looks like a key hole when the cover is off. There is a rail or bar that goes through the top of each carburetor that a control arm attaches to and moves the throttle needles. All of the needles are controlled by the one bar. I hope I'm making since as I am very new to this. I will attempt to attach a picture of the carbs. If these are the PD42 carbs I would greatly appreciate pictures of the choke springs etc...

Yup. Those are the PDs. You can actually see the marking PD on that second picture of yours. I'll try and get some pictures up to my flickr account asap.
 
 
Those pictures helped tremendously with the round spring! Here is a picture of the other really small spring that goes somewhere? I have no clue as it fell off during disassembly...sorry! CAM00291 (1).jpg
 
On second and third thought would you please send me pictures of the three spaces between the carbs at different angles. I keep running into additional problems and figured I wouldn't have to bug you every 5 minutes. Thank you very much for your assistance and patience!
 
That small spring connects the arm that control the throttle slide inside each carb with the actual throttle. You should have 4 of those small springs. I think I've got a picture of that online already. Let me check.
 
This is an old picture of mine but it might get you an idea of where to put that small spring. It prevents the throttle slide from turning/coming loose from the arms that is rotated by the throttle axle that goes through ever carb.
I can't get you any more pictures till tomorrow since that's when I'll get back to my shop. It's aproaching midnight here now (in Sweden).

I'll check in here tomorrow and if you haven't got any help from anyone else yet, I'll get you those pictures.

Stabler - out.
 
 
Hello again Stabler! I am having more problems with these carbs than I ever anticipated. Got it running on choke only so I took the main jets back out to clean them again and now I got nothing but a few seconds of running. Do you have any clue where I can get a rebuild kit cheaper than the $50 or so for each carb? Thanks again for all of your help.
