Abstract (en)

A carburetor comprising a vacuum passageway (10a) connecting a low-speed system venturi (9) with a slow jet (11); a level detecting means (12) capable of detecting whether or not the level of a fuel column to be defined in the vacuum passageway (10a) is higher than a predetermined position; and a solenoid valve (14) capable of switching over the opening degree of a low-speed fuel passageway (15) in response to an output delivered from the level detecting means, in which a flow rate of fuel flowing through the low-speed fuel passageway (15) is controlled so that the level of the fuel column is held at a predetermined position and thereby the fuel having the flow rate suitable for a flow rate of suction air passing through the low-speed system venturi (9) is supplied to an intake bore.
