Abstract
PURPOSE:To facilitate fuel adjustment and prevent deflection by permitting a fuel nozzle to be shifted towards the rotary shaft of a rotary throttle valve and supporting the fuel nozzle onto a carburetor body and abutting the basic edge part of the fuel nozzle onto a low speed fuel adjusting member by a spring. CONSTITUTION:When a valve shaft 40 is turned by a throttle valve 2, a rotary throttle valve 14 is integrally turned through a pin 38, and the direction of a suction hole for an intake inlet 13 is changed, and the intake quantity is controlled. Further, the valve shaft 40 is shifted leftward against a spring 7 by the action of a ball 41 engaged with a cam surface 42. When a fuel metering needle valve 10 shifts leftward integrally with the valve shaft 40, the opening area of the injection port 36 of a fuel nozzle 12 increases, and the fuel quantity is increased. Therefore, when a low speed fuel adjusting member 24 is screwed in, the fuel nozzle 12 is projected inside the rotary throttle valve 14, together with a nozzle supporting member 19. Therefore, the opening area of the injection port 36 is reduced.
