Carburetor Help

Finally got around to rebuilding the carbs on the bike. Like an idiot, I didn't take pictures of everything before I totally dismantled it. Thought my Chilton's would be enough, but it wasn't. With help from some knowledgeable folks on the CB750 Yahoo! group, I was able to get everything back together.

Started the bike up this weekend and found that I have what appears to be a vaccuum problem. The bike cranks up fine if I have the choke on and will run if I keep the throttle and the choke on halfway. If I let off the throttle, I lose it (no matter where the choke is). If I push the choke in further than halfway, the bike dies (reguardless of throttle). I've got photos below of as much of the "affected area" as I could get. If anyone has any ideas or suggestions as to what might be going on, what hose is hooked up to the wrong spot, etc. please drop me a line and let me know.

I have the photos labeled. Each number refers to the same hose in each photo (ex. 1 points to the bowl overflow hoses on all photos). My terminology may be off on what some of the parts are, so I apologize in advance. You can click on each image and it will open a larger version. The colors are just so you differentiate one line from another. The photos of the carbs on the bike were taken with the bottom of the airbox removed so you could get a better view.
