Mikuni carb?

[Blue]

I recently purchased a 99 warrior it had been sitting for a couple years. Naturally I drained the tank and pulled the carb off to clean it out. I was careful to do so, but when I took it apart a small spring fell out. There were only two springs in it, minus the throttle linkage. I know the larger one is for the accellerater pump, but don't know where the small one goes. I've looked up diagrams with no luck. It will only fit in a couple places, does it go in the fuel mix screw? Any help would be greatly appreciated thanks

there is a spring with the air/fuel mix screw if that helps

Thanks that's where I put it, was the only logical place.
