Bottom one is the Idle Adjustment. Just a fine tuning of the fuel flow at idle. Then you have your low speed and high speed adjuster.

Set idle using the idle adjuster at the butterfly to the RPM's you want. Then you have to adjust the Idle Adjustment screw to where your idle is smooth and power transitions good from dead idle to about 1/4 throttle. Then your low and highs take over.

Mine wants to die when I try going from Idle to low and after that its fine. So should I adjust the Idle first and then adjust the low, and keep the high the same
