Remove and clean or replace the spark plug.
■
Adjust the spark plug electrode gap
to 0.024 0.028 inch (0.6-0.7 mm). If
the spark plug must be replaced, use
only an NGK CMR5H or equivalent
resistor type spark plug of the cor-
rect heat range.
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine's internal parts.
NOTE:
The NGK CMR5H also meets the require-
ments for electro magnetic compliance
(EMC).
Remove and replace the fuel filter
element.

the fuel line. If you discover damage
or deterioration, the unit should be
removed from service unitl it can be
inspected by a Shindaiwa-trained ser-
vice technician..
