CARBURETOR (see Figure 7):
If you think your carburetor needs adjusting, see your nearest
SEARS, ROEBUCK AND CO. (OR SEARS CANADA, INC.)
SERVICE CENTER. Engine performance should not be af­
fected at altitudes up to 7,000 feet. For operation at higher
elevations, contact your nearest SEARS, ROEBUCK AND CO.
(OR SEARS CANADA, INC.) SERVICE CENTER.
ENGINE SPEED:
NEVER TAMPER WITH ENGINE GOVERNOR WHICH IS FAC-
^TORY SET FOR PROPER ENGINE SPEED. OVERSPEEDING
ENGINE ABOVE FACTORY HIGH SPEED SETTING CAN BE
DANGEROUS.
CHANGING OF ENGINE-GOVERNED SPEED WILL VOID
ENGINE WARRANTY.
DRAIN FUEL INTO APPROVED CONTAINER OUTDOORS,
AWAY FROM OPEN FLAME. BE SURE ENGINE IS COOL. DO
NOT SMOKE.
Run engine until fuel tank is empty and engine stops due to lack
of fuel.
NOTE: If ‘Gasohol* has been used, complete above instruc­
tions and then put 1/2 pint of unleaded gasoline into fuel
tank and repeat above instructions.
NOTE: Fuel stabilizer (such as STA-BIL) is an acceptable
alternative in minimizing the formation of fuel gum
deposits during storage. Add stabilizer to gasoline in
fuel tank or storage container. Always follow mix ratio
found on stabilizer container. Run engine at least 10
minutes after adding stabilizer to allow it to reach
carburetor.

Change oil if it has not been changed in the last three (3) months.
See "CHANGE OIL” instructions in "MAINTENANCE” section.

GENERAL
Just as your automobile needs professional mechanical mainte­
nance from time to time, so does your Craftsman engine. Replace­
ment of the spark plug and air cleaner is made necessary by
NORMAL use. Professional Air-Cooled Engine Service is as close as
your nearest Sears Roebuck and Co. (or Sears Canada, I nc.) Service
Center.
A yearly check-up or tune-up by Sears is a good idea to avoid
breakdowns or delay... do it at the end of the season, then you're
ready for the next. We even prepare it for storage for you.
