Abstract
PURPOSE: To restrict waste of fuel and increase of noises, by reducing the length of a threaded portion of a adjust screw for controlling the opening of a throttle valve at the time of ilding operation as small as possible, and thereby disabling to increase the idle opening of the throttle valve excessively.
CONSTITUTION: An externally threaded portion 2 of an adjust screw 1 are threaded half-and-half in the body 3 of a carburetor and a nut 9. That is, side face A of the head of the externally threaded portion 2 is threaded into an internally threaded portion 4 in the body 3 of a carburetor while the opposite side face B of the portion 2 is threaded into a threaded portion E of a nut 9. Here, if arrangement of the manufacture is such that a throttle valve 7 is held at a position having a proper idle opening in the above state, the externally threaded portion 2 is disengaged from the internally threaded portion 4 when adjustment is made by the user to increase the engine speed at the idling operation, so that such an adjustment is rendered impossible. That is, it is disabled for the user to make an erroneous adjustment that may cause increasing of fuel consumption as well as increasing of noises.
