Spark Arrester Service
The spark arrester must be serviced every 100
hours to keep it functioning as designed.
If the engine has been running, the muffler will be
very hot. Allow the muffler to cool before servicing
the spark arrester.
1. Remove the four 5 x 18 mm bolts from the
recoil starter, and remove the recoil starter.
2. Disconnect the spark plug cap from the spark
plug. Pull the spark plug wire and the ignition
switch wire out of the retainers in the top cover.
3. Remove the two 5 x 22 mm bolts from the top
cover, and remove the top cover.
4. Remove the three 5 mm screws from the
muffler cover, and remove the muffler cover.
5. Remove the special screw from the exhaust
deflector, and remove the exhaust deflector.
6. Remove the special screw from the spark
arrester, and remove the spark arrester.
7. Use a brush to remove carbon deposits from
the spark arrester screen. Be careful to avoid
damaging the screen.
The spark arrester must be free of breaks and
holes. Replace the spark arrester if it is
damaged.
8. Install the spark arrester, mufflercover, top
cover, and recoil starter in the reverse order of
disassembly.
