Adjustments
Note:
Wait for all moving parts to stop and remove
spark plug wire before servicing, cleaning, or making
any adjustments to the unit.
Adjusting the Self-Propel
Drive
If the lawn mower does not self-propel or has a
tendency to creep forward when the control bail is
released, adjust the drive cable.
1.
Stop the engine and wait for all moving parts to
stop.
2.
Loosen the cable support nut (Figure 34).

4.
Tighten the nut on the cable support.
5.
Check the operation for desired drive control.
Note:
If the unit creeps forward without the bail
engaged or if the wheels spin when you lift the
rear wheels off the ground, the cable is too tight;
repeat steps 1 and 2.
Note:
Adjustment to obtain desired ground
speed at full bail travel may be made in order to
accommodate slower speeds.
Adjusting the Blade Brake
Cable
Adjust whenever a new blade brake cable assembly is
installed or if the blade control lock lever does not
operate properly or the BBC belt is replaced.
1.
Stop the engine and wait for all moving parts to
stop.
2.
Disconnect the wire from the spark plug.
3.
Remove and retain the front belt cover and its
four bolts. Remove any debris under the cover.
4.
Pull the cable until there is approximately 1/8
inch in slack. Do Not put tension on the spring.
