動燃料供給装置。 A diaphragm type carburetor that includes a starting fuel holding chamber that communicates with the intake passage of the carburetor through a starting mixture passage, an air bleed passage that connects to the holding chamber, and a starting pump that supplies fuel to the holding chamber. In the starting fuel supply device for the engine, the intake port of the starting pump is connected to a fuel supply passage from the fuel tank to a fuel valve installed in a constant pressure chamber of the carburetor, and the starting mixture passage is connected to the starting mixture passage. A normally open on-off valve that closes the passage in conjunction with the operation of the starting pump is provided, and the air bleed passage is provided with a check valve that prevents fuel from flowing out from the holding chamber. An overflow passage is opened in which the excess fuel supplied from the starter pump is returned to the fuel tank, and a normally closed check valve is installed in the middle of the overflow passage to prevent backflow from the fuel tank. A starting fuel supply device for a diaphragm carburetor, which is characterized by:
