An electronic control system for a carburetor, includes: a transmission device (24, 25) linked to a valve (7, 8); an electric actuator (20, 21) for driving the valve (7, 8); and an electronic control unit (12a) for controlling operation of the electric actuator (20, 21). The transmission device (24, 25), the electric actuator (20, 21) and the electronic control unit (12a) are housed and held in a casing (10) mounted on the carburetor (C).. The ventilation means (72, 74, 74', 89, 90) for causing an interior of the casing (10) to communicate with the outside is connected to the casing (10). Therefore, it is possible to house the transmission device, the electric actuator and the electronic control unit efficiently in a common casing so as to downsize the electronic control system for a carburetor, and improve durability of the electronic control unit and the electric actuator. |
