料制御装置。 Feedback control that controls the air-fuel ratio supplied to the combustion chamber to a predetermined target air-fuel ratio by driving a control valve provided in the fuel control passage of the carburetor based on a signal from an air-fuel ratio detection means that detects the air-fuel ratio. In a fuel control device for an engine equipped with a carburetor, there is an acceleration determining means for determining an acceleration state from idling operation, and an air-fuel ratio is controlled for a predetermined period after a predetermined period of time has elapsed from the start of acceleration based on a signal from the acceleration determining means. 1. A fuel control device for an engine, comprising: control means for outputting a signal for correcting a target air-fuel ratio to a predetermined amount richer side to a control valve of the carburetor.
