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 Service Center.
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 your nearest 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.
The spark plug is housed in the engine
compartment under the top cover and
cannot be seen under normal condi-
tions.
1. Open the spark plug access door
on the control panel (Figure 15).
2. The spark plug and wire are now
visible.
3. Remove the spark plug wire.
4. Clean the area around the spark
plug base to prevent dirt from enter-
ing the engine when the spark plug
is removed.
5. Remove the spark plug.
6. Check the spark plug. If the spark
plug is cracked, fouled or dirty, it
must be replaced.
7. Set the gap between the electrodes
of the new spark plug at .030 inch
(Figure 16).
8.
Install the spark plug in the cylinder
head and firmly tighten.
