only component requiring routine
service. The standard spark plug for

gap for CS4-12, CV16, SV470-610,
and all twin-cylinder engines is .75
mm (.030"). Torque the spark plugs to
20 N·m (14 ft. lbs.) on CS4-12
engines; to 28 N·m (20 ft. lbs.) on
SV470-610 and all twin-cylinder
engines; and to 40 N·m (30 ft. lbs.) on
