Abstract

PURPOSE:To obtain a required characteristic of torque and output, by detachably installing a throttle substance to the air intake path. CONSTITUTION:In the downstream side of a throttle valve 31 in a carburetor 30, is installed a ring-shape throttle substance 40, having an inner hole with its diameter gradually reduced toward its center portion. This throttle substance 40 is inserted from an opening 30b at the downstream side of the carburetor 30, and its flange part 40a is put between the opening end 30b at the downstream side, and a link tube 20, screwed to the carburetor 30, and being fixed. Accordingly, the throttle substance 40 can be freely detached with said link tube if removed from the carburetor. So with a control made operable for mixture amount that passes through the air intake path P, a required torque characteristic can be provided.
