High Idle Speed Adjustment
The recommended maximum no-load high idle speed
for the CS engines is 3750 +100 RPM for tapered
shaft models, and 3800 +100 RPM for all others. The
actual high idle speed depends on the application.
Refer to the equipment manufacturer's instructions for
specific information.
The high idle speed is set by turning the throttle stop
screw on the throttle lever bracket assembly in or out.
See Figures 5-12 and 5-13 and follow the procedures
below.
1. Start the engine and allow it to warm up. Place the
throttle control lever into the ‘‘fast’’ or high idle
position.
2. Check the engine speed with a tachometer.
3. To increase the high idle speed–turn the high
idle speed adjusting screw out
(counterclockwise), while applying light pressure
to the throttle control lever in the counterclockwise
direction (away from the carburetor).
To decrease the high idle speed–turn the high
idle speed adjusting screw in (clockwise), until the
desired engine speed is attained.
