The fuel cap contains a non-serviceable fi lter and a
check valve. A clogged fuel fi lter will cause poor engine
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or
fi lter clogged.
SPARK PLUG REPLACEMENT
See fi gure 10.
WARNING
The material of the spark plug is metal. It becomes very
hot after you stop the engine. Wait for the engine to cool
down before disassembling the metal spark plug boot to
avoid personal injury.
NOTE:
This engine uses a Champion RCJ-6Y or
equivalent with 0.63 mm (0.025 in.) electrode gap. Use an
exact replacement and replace annually.
1. Stop the engine.
2. Hold the front portion of the rubber protect boot and
pull it away from the housing.
3. Pull the rubber protect boot upward to release the
hook.
4. Twist the metal spark plug boot and pull it away from
the spark plug.
5. Loosen the spark plug by turning it counter clockwise
with a wrench. Remove the old spark plug and replace
with a new one. Assemble back the metal spark plug
boot and the rubber protect boot.
