So, I had to take to two carbs apart to install the "T" vent hose part. Now I can't get the two valve to sync again. I think that I may have the throttle valve control lever in wrong. The carb you would attach the throttle cable to (right side) is showing one dot, and the other is showing more than one even if I turn the sync screw all the way down.
Here are some pictures.

What am I doing wrong?? Please Help!!
I think the lower spring needs to be moved to the arrow??
My GS is gone, otherwise I would take a look...I am totally shooting from the hip :dunno_black:

EDIT:.....It looks like you have it right, did you have the screw out all the way? Maybe you need to switch the spring under the screw, they look like they might be different diameters??

Those springs are correct. You screw in the screw to change the relative positions of the two carbs --- that is the carb sync/balance screw. Right now the carbs would be very much out of balance. Screw it in about 3 full turns to start or screw in enough so the butterflies look like they are in the same positions.
Thanks for the help guys! I really appreciate it.
So oddly before removing the crabs from one another they were in sync but now no matter what I do I can't seem to get them even close. The sync screw will only go so far before the spring is fully compressed. Is there something else that can get out of whack between the valve control lever and the other carb?
When you sync the carbs, be sure the tube to the petcock is either connected to the petcock or capped off. If left open, the left carb will have a "vacuum leak".
Has anyone ever reassembled the valve control lever in these pictures? Any tips? I am still having issues.
I see in your picture the carb on the right has the butterfly more open than the left. Turning in the screw will balance them.
It may be other issues you are having since you had everything taken apart, and not the carb sync issue.
Visually match them as your starting point. Look at the small jets in the throat as your guide for visually balancing the butterflies.
