A four stroke single cylinder combustion engine starting system with an electrical machine is operable as both a generator and a motor. The starting system has a single cylinder four stroke combustion engine. A piston of the engine is coupled to a shaft of the electrical machine. The starting system also has a motor driver having outputs coupled to the electrical machine. A controller is coupled to the driver and an ignition switch is coupled to the controller. In response to the controller receiving an ignition signal from the ignition switch, the driver controls the electrical machine to operate as a motor so that the electrical machine rotates in a reverse direction to move the piston in a reverse stroke cycle. After the piston reverses to a power stroke position of the reverse stroke cycle the driver controls electrical machine to rotate in a forward direction to move the piston in a forward stroke cycle to attempt to ignite the combustion engine.
