Setting the idle speed on the Pro .15 Engine
SETTING THE IDLE SPEED
The idle screw regulates the throttle opening to control the idle speed. The throttle opening at idle should be set as shown in the drawing. The opening should be 1 to 1 1/2 millimeters at the widest point in the opening.
Make sure that the throttle trim on the transmitter is adjusted correctly so that the throttle arm actually rests against the idle stop screw. Do not attempt to control your idle speed with the throttle trim control on the transmitter. The idle speed may need to be readjusted after the engine is warm.
