Throttle Control Adjustment
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 lever to the SLOW position.
3.Loosen throttle cable screw securing the throttle
cable to the governor lever.
Note: Engine speed is measured at the input drive
pulley (Fig. 6). Actual engine speed is twice the input
drive pulley speed.
4.The governor lever will move to the slow idle posi-
tion if it is improperly adjusted.
A. Check low idle speed setting with a tachometer.
Low idle speed should be 750 to 850 rpm. Adjust
low speed idle screw in or out to attain the correct
speed setting.
B. Check high idle speed setting with a tachometer.
High idle speed should be 1750 to 1850 rpm. Ad-
just high speed idle screw in or out to attain the cor-
rect speed setting.
