とを特徴とする気化器付エンジンの空燃比制御装置。It is equipped with an auxiliary air supply passage that supplies auxiliary air to the intake system when the engine ambient temperature is above a set value, and a diaphragm device for compensating for complete explosion that is activated by detecting the complete explosion of the engine is attached to the carburetor choke valve. In the engine equipped with a carburetor, an on-off valve is linked to the operating rod of the complete explosion correction diaphragm device to open the auxiliary air supply passage when the diaphragm device is not in operation, and to reduce the passage area of the auxiliary air supply passage when the diaphragm device is in operation. is interposed in the auxiliary air supply passage, and is connected to a member that is linked to the opening and closing of the carburetor throttle valve, and is connected to the opening/closing valve when the carburetor throttle valve is opened beyond the set opening degree. 1. An air-fuel ratio control device for an engine with a carburetor, characterized in that a detent is provided that engages with a valve operating rod to prevent movement of an on-off valve in the opening direction.
