im confused. i see people using the term idle speed and baseline idle interchangeably here, but both are in terms of RPM. baseline is set by the idle adjustment screw, and idle speed by the air bleeds. but i thought the bleeds were to be exclusively used to set the idle speed (and balance)? If you set the baseline to 1200RPM with the idle screw, what additional adjustment for speed would the bleeds even need to do?
