1-20. (canceled)
A starting system for an engine having a crankshaft with a first end and a second end, comprising:
- a first ratchet mechanism operatively connected to the first end of the crankshaft;
- a recoil-type manual pulley;
- a first cam assembly configured to selectively engage the first ratchet mechanism;
- an electric motor configured to be selectively energized;
- a second ratchet mechanism operatively connected to the second end of the crankshaft;
- a second cam assembly configured to selectively engage the second ratchet mechanism when the electric motor is energized to start the engine, and configured to be disengaged from the second ratchet mechanism when the engine is started without energizing the electric motor;
- and
- wherein the first cam assembly is further configured to be disengaged from the first ratchet mechanism when the electric motor is energized.

A starting system for an engine having a crankshaft with a first end and a second end, comprising:
- a manual starter operatively connected to the first end of the crankshaft to rotate the crankshaft to start the engine, the manual starter including
- a first centrifugal clutch;
- a first cam assembly configured to selectively engage the first centrifugal clutch;
- an electric starter operatively connected to the second end of the crankshaft to rotate the crankshaft independently of the manual starter, the electric starter including
- a second centrifugal clutch;
- a second cam assembly configured to selectively engage the second centrifugal clutch;
- wherein the first centrifugal clutch is configured to be engaged with the first cam assembly when the manual starter is operated to start the engine, and is configured to be disengaged from the first cam assembly when the electric starter is operated to start the engine;
- and
- wherein the second centrifugal clutch is configured to be engaged with the second cam assembly when the electric starter is operated start the engine, and is configured to be disengaged from the second cam assembly when the manual starter is operated to start the engine.
