Removed the carbs last night and started disassembling them. I noticed that the rotator shaft/assembly seems to bind somewhat when I rotate the throttle wheel. When the carbs were still mounted on the bike, I always assumed that the throttle was just old and stiff and needed some help rotating back to idle. But now after removing the carb assembly, it seems like the PO may have installed/mounted them wrong. I also disconnected the needle cylinders from the linkage to see if they were causing it but it still binds. I cleaned out the parts that rotate on the shaft with a nylon brush and some lubricant, but still binds. I then loosened all 8 screws on the back of the bracket that all of the carbs mount to and it seems to move a little more freely, but still stiff and binds some. Should I go ahead and completely remove each carb and see if that shows the problem? Am thinking that somehow they are getting torsion on them or they are not aligned properly. Also, I noticed that there is a small metal bracket between 2 of the carbs that is bent upward a little. See photo. Any suggestions?
