• Disconnect the spark plug wire and keep it away from the spark plug.
• Disconnect battery at negative terminal (only engines with electric start.)
• Use only correct tools.
• Do not tamper with governor spring, links or other parts to increase engine
speed.
• Replacement parts must be the same and installed in the same position as the
original parts.
• Do not strike the flywheel with a hammer or hard object because the flywheel
