Abstract

PURPOSE: To make it possible to set an air-fuel ratio at a start or others fairly thick by providing an one-direction time delaying device in a negative pressure passage to the chamber in a fuel feeder having a chamber which varies a passage resistance of a fuel feed passage.
CONSTITUTION: A float chamber 21 of a fuel feeder is connected to a main fuel nozzle 17 through a fuel feed passage 44 and an air bleeder 23 from a main jet 22 on one side, and on the other connected to a fuel nozzle 20 through a jet 24 and an air bleeder 25. The float chamber 21 is also connected to the air bleeder through a passage 27 having a chamber that is a power valve 26. In this case, an one-direction time delaying device 36 which gives a delay to the transmission of negative pressure to a negative pressure chamber 33 is provided in a negative pressure passage 35 which connects the negative pressure chamber 33 divided by a diaphragm of the power valve 26 to a primary intake passage 10 in the downstream of a throttle valve 13.
