Abstract:

To reduce the manufacturing cost of a carburetor with an acceleration pump by reducing the number of steps for installing an acceleration pump mechanism.

This carburetor 1A with an acceleration fuel pump is provided with the acceleration pump mechanism which has a cylinder 15 to which a fuel suction passage 17A for introducing fuel from a float chamber is connected, a piston 13 inserted into the cylinder 15 and vertically slid interlocking with the opening/closing operation of a throttle valve 11, an acceleration fuel passage 18 for delivering fuel compressed by the piston 13 to the side of an intake passage, and a return fuel passage for returning a part of fuel in the cylinder 15 to the float chamber. The fuel suction passage 17A doubles as the return fuel passage for returning the excess fuel to be delivered to the float chamber when delivering acceleration fuel by arranging a metering jet 170a in the fuel suction passage.
