Spring & Ball Choke Stop Solution

When I rebuilt the carbs a small spring and ball came out near the choke. I could not figure out where the came from, and I felt like a fool because of it. I started searching the web and found many people with the same experience, but no solutions. Then a friend at work remembered this page: http://www.xs650.com/forum/showthread.php?t=9285. Hot Damn. It works.
