FUEL FILTER Use a wire hook to extract the
fuel filter from inside the fuel tank, and then
remove and wash the filter element in clean
fuel. Before reinstalling the filter, inspect
the condition of the fuel line. If damage or
deterioration is noted, the vacuum should
be removed from service until it can be
inspected by a trained service technician.
COOLING SYSTEM Remove the engine
cover (as described under "Spark Arrestor"),
and use a wood or plastic scraper and a soft
brush to remove dirt and debris from the
cylinder fins and crankcase.
SPARK ARRESTOR MAINTENANCE
Hard starting or gradual loss of performance
can be caused by carbon deposits lodged
in the spark arrestor screen. For maximum
performance, the spark arrestor screen
should be periodically cleaned as follows:
1. Remove the spark plug.
2. Remove three self- tapping screws and
two machine screws from the engine cover,
and then gently move the engine cover
aside.
3. Remove the three-spark arrestor
retaining screws, and then remove the spark
arrestor cover, screen, gasket, and chamber.
4. Use a plastic scraper or wire brush to
remove carbon deposits from the arrestor
screen, chamber, and cover.
5. Inspect the screen carefully, and replace
any screen that has been perforated,
distorted, or is otherwise unserviceable.
6. Install the chamber, screen, gasket and
cover in the reverse order of disassembly,
and then install and securely tighten the
three cover retaining screws.
7. Install the engine cover, and verify that
the fuel line connections are still tightly in
place.
8. Install the engine cover retaining screws
in the reverse order of removal, and tighten
Securely.
9. Install and tighten the spark plug, and
reconnect the spark plug wire.
