Abstract

PURPOSE: To prevent uneconomical operation in such a way that when a throttle valve is at the opening operation, negative pressure from the air inlet path is communicated to a high carbureting float chamber in order to stop feeding high carbureting fuel to the idle port.
CONSTITUTION: The first float chamber 4 to hold low carbureting fuel which opens its port to an air inlet path 1 is communicated to a bypass port chamber 8 which opens bypass ports 9a, 9b which face the air inlet path 1, and the second float chamber 15 to hold high carbureting fuel which communicates through a communicating path to the chamber 8 is communicated to an idle port 20. Since the second float chamber 15 which fully opens a throttle valve 2, and becomes more than the atmospheric pressure in response to the bypass ports 9a, 9b which receive positive pressure becomes negative pressure by receiving air inlet negative pressure ensuing after opening action of the throttle valve 2, and keeps balance with the pressure from the idle port 20, there is no cause to suck up the high carbureting fuel into the idle port 20.
