Hey guys, I wanted to see if anyone has run into the same issue. I have a 78 CB750k with the keyhole carbs. When I first pulled them off the bike to clean they would open an snap back closed perfectly using the linkage where the throttle push/pull cables attach. Now when I open more than half way it gets hung up and stuck? I'm confused because the actual slides are not catching and when I open the top of each carb and unscrew the arm holding the slides they move freely perfectly. Is it an issue with the return spring (large one) or does it need to be lubricated somehow?? Any help with this would be greatly appreciated. Thanks
