If a new throttle cable must be installed or the cable is
out of adjustment, adjust the cable as follows:
1. Park mower on a level surface. Make sure engine is
OFF. Remove high tension lead from the spark plug.
2. Move throttle control lever on the handle to the FAST
position.
3. Loosen throttle cable screw securing the throttle
cable to the governor lever.
4. Make sure throttle lever is in the FAST position and
the governor lever is against the high speed idle screw.
5. Tighten throttle cable screw securing the throttle
cable to the governor lever.
6. After cable adjustment, connect high tension lead to
spark plug, start engine, and check engine speed with
a tachometer:
A. Low idle speed should be 2300 to 2500 rpm.
Adjust low speed idle screw in or out to attain the cor-
rect low idle speed setting.
B. High idle speed should be 3500 to 3700 rpm.
