Ok guys help me out i need to know how to take that little neddle valve knob that keeps the motor from going to lean or rich off. I am at high elevation and it is way to rich up here. Any help or pictures would be great!!!!

It takes a small metric Hex key type allen wrench to loosen a set screw on the collar. Move it to whatever position you like or remove it. Whatever.

Here is the high speed collar...

You can see the set screw on each one.

Enjoy,
