Move the Wheels/Tines/PTO Drive Lever to NEUTRAL.
The switch body on the bottom of the engine mount
tab should be resting squarely on top of the reverse
adjustment bolt, and the reverse disc should be at least
⁄” away from the transmission drive pulley. See Fig. 6-19.
If the reverse disc is any closer than this, raise the reverse
adjustment bolt (turn it counterclockwise).
Check that reverse disc is at least ⁄” away from
transmission drive pulley. Then hold reverse adjustment
bolt steady with one wrench while tightening the jam nut
with a second wrench. See Fig. 6-23.
Place a chalk or pencil mark on the top edge of the plunger
retaining bolt. Now, while watching the mark, loosen the
bolt ⁄-turn. See Fig. 6-24. Do not exceed a ⁄ turn. This
would disengage the bolt from the locking groove in the
side of the plunger.
Hold the plunger retaining bolt steady with a wrench while
tightening the jam nut against the side of the plunger
housing. See Fig. 6-22.
Check the action of the reverse disc as explained
previously.
NOTE: If the above adjustments have not corrected an
improperly working reverse drive, contact an authorized
dealer or Factory Technical Service Department for
assistance.
Throttle Cable
The throttle lever settings are factory adjusted, so unnecessary
adjustments should not be made. However, if the engine does
not start or stop, or respond immediately to various throttle lever
settings, then adjustments may be necessary. Please refer to the
Engine Operator’s Manual supplied with your tiller for specific
adjustment instructions.

Ignition System
Your engine is equipped with an electronic ignition. It does
not have a condenser or points, so there is no need to perform
any regular tune-up maintenance on this system other than
adjusting or replacing the spark plug.
Spark Plug
The spark plug must be in good condition for proper
engine operation. Remove and inspect the plug every 50
operating hours or annually, whichever occurs first. The
correct electrode gap is .030”. Check the gap with a feeler
gauge. Do not use a spark plug if the porcelain is cracked,
the electrodes are pitted or burned, or if other visible
damage is present.
NOTE: Do not wire brush or sandblast the spark plug to
clean it — loose particles can enter the engine, causing
damage. To replace the plug, first tighten it securely by
hand, then use a spark plug wrench to tighten the plug an
extra ⁄ turn.
Off-Season Storage
When your tiller will not be used during the off-season, prepare it
for storage with the following steps:
Clean the tiller and the engine.
Do routine tiller lubrication and check for loose hardware.
Protect the engine from deterioration or damage by
referring to the engine storage instructions in your engine
manual literature.
When engine is still warm, drain oil from engine crankcase.
Refill with fresh motor oil.
Protect the internal cylinder against rust by removing the
spark plug and pouring one ounce of clean engine oil into
spark plug hole. Then slowly pull out the recoil start rope
2 or 3 times to distribute the oil internally. Replace spark
plug, but do not reconnect the plug wire. Pull the rope
until resistance is felt — let rope rewind.
Charge the battery (electric start option). Store the battery
in cool, dry location.
Move the Wheels/Tines/PTO Drive Lever to NEUTRAL
position. Keep the tiller in a clean, dry area.
Never store the tiller with fuel in the fuel tank in an
enclosed area where gas fumes could reach an open flame
or spark, or where ignition sources are present (space
heaters, hot water heaters, furnaces, etc.).
