FUEL FILTER INSPECTION

Check the fuel filter if required. A contaminated fuel filter
restricts the fuel supply. Clean or replace the contaminated
filter. Replace a damaged filter in any case.
1. Remove the clamp.
FUEL HOSE
2. Pull off the fuel hose and pull the fuel filter out of the fuel
hose.
Slight contamination: full the fuel filter from the
fuel line and clean it in petroleum ether.
Bad contamination: Replace the fuel filter.

3. Inspect the spark plug. Replace the spark plug if the
electrodes or the insulator are damaged.
4. Measure the electrode gap with an appropriate feeler gauge.
The gap must be 0.70 – 0.80 mm. Correct the gap, if
necessary, by carefully bending the outer electrode slightly.
5. Carefully screw in the spark plug by hand to prevent
stripping the thread.
6. Tighten the spark plug with the spark plug wrench after it is
seated.
If you are installing a used spark plug, tighten it by 1/8 – 1/4
turn.
If you are installing a new spark plug, tighten it by 1/2 – 1/4
turn.
A loose spark plug may overheat and damage the engine.
Tightening the spark plug too firmly may damage the thread
in the cylinder head.
7. Put the spark plug connector back in place.
