Abstract

A starter system (400), for an internal combustion engine (200) including a carburetor (450) and a recoil starter (150), may include a sensor (420), a controller (430) and an actuator (440). The carburetor (450) may have at least a choke valve (322) for controlling a flow of a fresh air into a combustion chamber (232) of the engine (200) during engine start. The choke valve (322) may have a choke position and an open position and may be positioned into the choke position at engine start. The recoil starter (150) may start a rotation of an engine crankshaft causing a fuel supply to the combustion chamber (232) of the engine (200). The sensor (420) may be disposed to detect movement parameters associated with the engine (200) or crankshaft responsive to operation of the recoil starter (150). The controller (430) may be operably coupled to the sensor (420) to receive information indicative of the movement parameters and providing a control signal based on processed information providing an indication of an optimal condition for engine start. The actuator (440) may be configured to receive the control signal from the controller (430) and to initiate automatic repositioning of the choke valve (322) from the choke position to the open position based on receiving the control signal from the controller (430) responsive to the indication of the optimal condition for engine start.
