ABSTRACT:
The present invention provides a device for controlling the air/fuel mixture ratio during the starting period for an outboard motor. Specifically, a positive temperature coefficient (PTC) heater controls a fuel flow regulating valve at an engine's charge forming device. A multipolar generator is used as an exclusive power source for the PTC heater. The arrangement of the invention has a relatively simple construction and can be used with propulsion units which do not have batteries.
