ABSTRACT:
A carburetor is provided that supplies an appropriate amount of fuel at engine start-up and in a specific range of rotational speed, and allows stable engine operation at a target rotational speed. The carburetor comprises a first fuel system (F1) for metering fuel from the constant fuel chamber (18) with a metering needle (32) linked to a throttle valve (5), and delivering the fuel to an air intake passage (2); and a second fuel system (F2) for controlling fuel compressed by a fuel pump (8) with an electromagnetically driven control valve (52) and delivering the fuel to the air intake passage (2); by supplying pressured fuel controlled by the control valve (52) in a predetermined specific range of rotation and controlling the rotational speed during start-up and warm-up, a target rotational speed can be maintained.
