I removed my VT500 carbs for cleaning and now when I've replaced, the choke cable has play on the close position and the engine races. It appears that the dividing junction does not hold the cables secure so you can push the cable back out. The free ends of the dual end only retract. You have to pull them to extend. The spring on the valve stopper isn't long enough to pull the cable ends all the way out. How are these supposed to work?
