vals shown in the maintenance chart,
clean the spark arrester as follows.

1. Remove the bolts

and pull out

the spark arrester

2. Use a brush to remove carbon

deposits from the spark arrester
screen. Be careful not to damage
the spark arrester screen. Check
that the screen has no holes or
tears.

3. Reinstall the spark arrester in

reverse order of removal.



WARNING

You can be burned if you touch
the hot muffler.

Wait until the muffler cools to
