CLEANING THE ENGINE
See Figures 67 - 68.
Clean the cylinder fins and flywheel fins with
compressed air or a brush periodically. Danger-
ous overheating of the engine may occur due to
impurities on the cylinder.
WARNING:

in place.
Because parts can fracture and pose a danger
of thrown objects, leave repairs of the flywheel

be blocked with carbon deposits. These deposits
may need to be removed to restore performance.
