FEATURES

Centrifugal Clutch

The centrifugal clutch automatically engages and transmits power
when engine speed is increased above approximately 4,000 rpm. At
idle speed, the clutch is disengaged.
Do not run the engine without mounting it on equipment that includes
the centrifugal clutch drum and housing, or centrifugal force will cause
the clutch shoes to contact and damage the engine case.
