Remove and clean or replace the
spark plug.
Adjust the spark plug electrode gap
■
to 0.024 inch (0.6 mm). If the spark
plug must be replaced, use only an
NGK CMR5H or equivalent resistor
type spark plug of the correct heat
range.
CAUTION!
Make sure you do not pierce the fuel
line with the end of the hooked wire.
The line is delicate and can be dam-
aged easily.
Clean the spark plug
and check the gap at
the electrode.

requirements for electro magnetic com-
pliance (EMC).
Remove and replace the fuel lter
element.
Use a hooked wire to extract the ■
fuel lter from inside the fuel tank.
Inspect the fuel lter element. If it

recommended that this is done
by a Shindaiwa-trained service
technician.
Replace the spark plug annually.
