ADJUSTING THE IDLE SPEED
If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
NOTE: Make sure the choke lever is NOT engaged while adjusting
the idle speed.
• If the engine stops, increase the idle speed. Use a small
Phillips screwdriver to turn the idle speed screw clockwise,
1/8 of a turn at a time, until the engin
e idles smoothly (Fig. 21).

f the cutting head spins when the engine idles, reduce the idle
speed. Turn the idle speed screw counterclockwise, 1/8 of a
turn at a time, until the cutting head stops moving (Fig. 21).
WARNING:
The cutting head may spin during idle speed
adjustments. Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
