An engine starter comprising:
- a starter motor having an output shaft;
- a pinion fixed to the output shaft and driven by the starter motor;
- a ring gear meshingly engaged to the pinion;
- a shoe-engagement structure coupled to the ring gear;
- a flex plate that is adapted to be coupled to an engine crankshaft for common rotation;
- an arm coupled to the flex plate for pivoting motion about a pivot point, the arm having a shoe and a counter mass;
- and
- a spring biasing the arm about the pivot point to urge the shoe toward the shoe-engagement structure;
- wherein the counter mass is configured to counteract the spring and drive the shoe away from the shoe-engagement structure when a rotational speed of the flex plate is greater than or equal to a predetermined rotational speed.
