ラム式気化器を備えたエンジンの始動装置。 In an engine equipped with a diaphragm carburetor, a starting fuel chamber is provided that communicates with the main fuel chamber of the diaphragm carburetor, and a starting fuel chamber is provided in an upper part of the starting fuel chamber that communicates with the intake passage downstream of the throttle valve. At the same time as the air passage is opened, a starting air passage is opened at the bottom of the starting fuel chamber, and this starting fuel chamber is further partitioned by a diaphragm to form a negative pressure chamber at the back, and this diaphragm has the starting air passage opened at the bottom of the starting fuel chamber. An on-off valve is installed to connect and disconnect the communication path between the fuel chamber and the main fuel chamber, while a spring is installed in the negative pressure chamber to tend to normally close the on-off valve, and this negative pressure chamber is connected to the engine recoil starter. An engine starting device equipped with a diaphragm carburetor, characterized in that it is connected to a negative pressure pump that operates in conjunction with the diaphragm carburetor.
