御装置。 This is a control device for a carburetor that has a slow port whose opening area is adjusted by a throttle valve, and feeds back the amount of fuel from the carburetor so that the air-fuel ratio of the mixture supplied from the carburetor reaches a set value during engine operation. an air-fuel ratio control means for controlling the opening of the throttle valve; and an opening control means for controlling the opening of the throttle valve so that the idle speed of the engine becomes a set value; 1. A control device for a carburetor, comprising a fuel amount correction means for correcting the amount of fuel supplied from the carburetor based on the air-fuel ratio control means, independently of the air-fuel ratio control means.
