PURPOSE: To provide an engine starting device which can feed an extra volume of fuel into an engine at low temperature starting so as to facilitate the start of the engine, by using an accelerating pump linked to a throttle valve in a carburetor.
CONSTITUTION: In a starting device in which fuel is mixed into air within a carburetor 1 and is then fed into an engine, a lever 5 is associated with the operation of a throttle manipulating piece 3 so as to push a plunger 10 in an accelerating pump 9 in order to feed accelerating fuel, and a second lever 8 adapted to be operated by a solenoid 7 is laid between the lever 5 and the plunger 10 so that the solenoid 7 energized by a thermosensor or the like pushes the plunger 10 through the intermediary of the second lever 8, thereby it is possible to feed an extra volume of fuel.
