Description from the creator

Request by jchan123 on how to the adjust the Idle Speed Screw on a Trimmer/leaf blower. I use my Stihl BR420 backpack blower as an example

As the name implies.. the idle screw's function is to alter the idle speed of the engine when its idling (not under load)...It doesn't affect its operation at full throttle. While the engine is running..turning the LA screw in (clockwise) causes the motor to idle faster and turning it opposite causes it to idle slower.
