COMBUSTION CHAMBER CLEANING
Remove the cylinder (page 14-2).

the inner wall of the cylinder, and insert the paper into
the cylinder.
Attach the cleaning brush (special tool) (2) to an electric
drill and clean any carbon deposits from the combustion
chamber.
• Do not remove valves from the cylinder while
cleaning the combustion chamber.
• Be sure to insert a thick paper into the cylinder to
protect the inner wall of the cylinder during clearing
of the combustion chamber.
• Do not press the cleaning brush with force against
the combustion chamber.
