not only enhance its appearance but will improve
its general performance and extend the useful life
of many components.

vent water entry. A plastic bag and strong
rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy, ap-
ply degreaser with a paint brush. Do not ap-
ply degreaser to the chain, sprockets or
wheel axles.

hose. Use only enough pressure to do the
job.
