One way to make sure the idle micro is adjusted correctly AND functioning is to remove the wires going to it (make a sketch or just try to remember which wires go where) and hook a meter to the terminals of the switch. Set the meter on continuity or a low resistance scale and at idle it should read closed. Now rotate the throttle spool and the switch should open. When you release the throttle spool the switch should consistantly read closed. When you are done hook the wires back up. Do this with the motor OFF.
