Abstract: A system for starting model engines. The model engine starting system, in the preferred form, utilizes a motor to drive a torque converting unit. The output of the torque converting unit is mechanically coupled to the crankshaft of an engine through an overrunning clutch so that rotation and torque from the torque converting unit is transmitted to the crankshaft. There is, however, no transmission of rotation or torque in the reverse direction when the engine is running. For glow ignition model engines, a system is described which assists the starting system by controlling the temperature of the glow plug, thus maintaining proper ignition of fuel during starting and running the engine. In order to control the temperature of the glow plug, a control system is utilized to vary the electrical power delivered to the glow plug according to the glow plug's temperature.
