To Adjust The Carburetor; To Adjust Or Replace The Spark Plug - Craftsman 536.885213 Operator's Manual

TO ADJUST THE CARBURETOR
The carburetor is not adjustable. En-
gine performance should not be af-
fected at altitudes up to 7,000 feet. For
operation at higher elevations, contact
your nearest Sears Store.
IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed. Over-speeding
the engine above the factory high
speed setting can be dangerous. If the
engine-governed high speed needs an
adjustment, contact an authorized
Sears Service Center. They have the
proper equipment and experience to
make any necessary adjustments.
TO ADJUST OR REPLACE THE SPARK PLUG
Check the spark plug every twenty-
five (25) hours. Replace the spark plug
if the electrodes are pitted or burned or
if the porcelain is cracked.

compartment under the top cover and
cannot be seen under normal condi-
tions.

ing the engine when the spark plug

mended torque is 18 to 20 foot
