Engine Care
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for a detailed list and instructions.
Maintain oil level as instructed in engine manual.
Service air cleaner every 25 hours under normal conditions.
Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding usually indicates
that the air cleaner should be serviced. To service the air
cleaner, refer to the engine manual.
Clean spark plug and reset the gap once a season. Spark
plug replacement is recommended at the start of each
mowing season. Check engine manual for correct plug
type and gap specifications.
Clean engine regularly with a cloth or brush. Keep the
top of the engine clean to permit proper air circulation.
Remove all grass, dirt, and combustible debris from muffler
area.

Adjustments
Variable Speed Cable
Periodic adjustment of the variable speed cable may be
necessary due to normal wear on the drive system. Adjustment is
needed if unit begins to run too slow or too fast.
Start engine and place shift lever in the third speed
position.
Stop engine, remove ignition key, and disconnect spark
plug wire and ground it against engine.
With engine off, shift back to first speed. This will provide
slack in the cable.
Carefully remove the harness assembly from the speed
control housing by removing the three screws securing it
to the housing. See Fig. 6-3.
