CARBURETOR ADJUSTMENTS STORAGE INSTRUaiONS
Do not make unnecessary adjustments. Factory set­
tings are correct for most applications. If adjustments
are needed, proceed as follows:
In event engine is to be stored for any length of time
(30 days or more) or at the end of mowing season, pre­
pare as follows:
1. Close power adjusting needle (figure 41 or figure
42) by turning to right (clockwise). Close finger
tight only. Forcing will cause damage.
2. Open one turn (counterclockwise).
3. Close idle adjusting needle (figure 41 or figure
42), by turning to right (clockwise). Close finger
tight only. Forcing will cause damage.

wise (figure 41 or figure 42).
5. Start engine. Follow starting instructions.
6. With throttle open (carburetor control at RUN or
FAST position), adjust power adjusting needle one-
eighth ('/s) turn at a time forward or backward un­
til engine runs smoothly. If engine tends to stall
under load, enrich slightly (counterclockwise).
1. Drain gas tank completely by removing fuel line
at the carburetor or fuel tank, whichever is easier.
CAUTION
Drain into container outdoors away
from fire or flame.
2. DRAIN CARBURETOR.
Drain by pressing upward on bowl drain (figure 7).
3. Inside protection of engine for storage is performed
by removing spark plug and pouring one ounce
of SAE 30 oil through spark plug hole into cylinder.
Crank engine without starting several times to
spread oil over cylinder walls.
IMPORTANT: A yearly checkup or tuneup by the SEARS
Service
Department is a good way of ensuring that
your rotary mower will provide maximum perform­
ance for the next season.
Store the rotary mower in a protected area and cover
the unit for additional protection.
ENGINE SERVICE
Unless the operator is fully qualified to make engine
adjustments and repairs, it is recommended that such
work
be done by technicians trained to work on
rotary mower type gasoline engines.
The Repair Parts section of this manual contains a list
of engine replacement parts and illustrations to assist
the trained technician in making repairs and ordering
proper replacement parts.
The following chart. Trouble Shooting, is provided as
a guide for correcting minor problems when the trou­
ble is known.
7. Hold throttle lever closed or move carburetor con­
trol to IDLE or SLOW position and adjust idle ad­
justing needle until engine runs smoothly, pro­
ceeding as in step 6 above.
8. Allow several seconds between each adjustment
when performing either step six (6) or seven (7)
to allow engine to react to new setting.
9. Maximum engine speeds are preset at factory and
should not be changed except by a qualified serv­
ice station repairman who has the necessary equip­
ment.
