PURPOSE:To make one side alone rejectable when either of an air bleed part or a spray part comes to machining defective and thereby aim at reduction in failure expenses, by constituting a main nozzle with the air bleed part and the spray part in a partitive manner, while forming this spray part with a plastic material. CONSTITUTION:A main nozzle is constituted of a spray part 11 in its tip end part and an air bleed part 12 ranging the former. And, a spray hole 13 is installed inside the spray part 11, and the upper outer circumference is inset in a hole of a carburetor body to be opened to a Vnturi aprt 6. In addition, the spray part 11 is made up of a plastic material. On the other hand, the air bleed part 12 is made up of metallic materials including aluminum and others, and a passage 14 is installed in the inside, while an air bleed hole 15 is installed in the passage 14 ranging from the outer circumference to the inside. And after machining for the spray part 11 and the air bleed part 12 is over, the spray part 11 is fitted in the air bleed part 12, thereby securing the desired main nozzle 10.
