CARBURETTOR ASSEMBLY

[Problem] To provide a carburettor assembly which suppresses dripping of fuel from a nozzle to an air-fuel mixing passage during idling. [Solution] The carburettor assembly comprises: a fuel chamber for storing a fuel for supply to an air-fuel mixing passage ; a nozzle which comprises a check valve and discharges the fuel to the air-fuel mixing passage , the nozzle being arranged at a position in the air-fuel mixing passage in which the fuel drops naturally; a plurality of holes for discharging the fuel to the air-fuel mixing passage during idling, at a position in an air-fuel mixture flow downstream from a position of the nozzle in the air-fuel mixing passage ; a fuel passage for connecting the fuel chamber and the nozzle and also connecting the fuel chamber and the plurality of holes ; and a resistor which is arranged in the fuel passage between the fuel chamber and the nozzle , and thereby forms resistance against a fuel flow directed to the nozzle
