Choke won't stay on

[Kirby]

While working on a friend's bike the other day, he mentioned that the choke wouldn't stay on by itself. After doing some searching on here, I couldn't find an answer as to how to get it to stay on without simply standing there holding the choke knob out. So I decided that there might be others out there with the same problem. Here's the solution. If you lay down on the floor and look up at the choke knob, just behind it(towards the rear of the bike) there is a hex nut that is held in place by a flat thin locking tab. It looks like a very thin flat washer. See picture below. All you have to do is take is a flat blade screwdriver and straighten out the tab that is holding the nut in place. Then with the appropriate wrench or even a pair of plyers, tighten the nut just enough to start holding the choke linkages in place. This shouldn't take tightening but maybe one flat on the nut. Afterwards, bend the tab back over at any place it's most convenient. Now your choke should stay on until you push it back in. Don't over tighten or it will be hard to push back in.

Seen this a dozen times, but I did not know there was a tab needing bent to adjust the nut. It (the nut) merely squeezes on the shaft much like a packing on a water spigot, excellent of you to bring this out, especially about the tab.

The tab was on my friend's '99 and on my '09 so I guess it's on all of them.
