how does the centrifugal clutch work?

At idle speed the clutch shoe is held from the sprocket drum by the spring tension. As the shaft turns faster the shoes overcome the spring tension by centrifugal force. The shoes move outward and contact the sprocket drum which causes the drum to turn at the same speed.
