Abstract
A vaporized fuel controller for a carburetor which utilizes the negative pressure in the intake manifold and electromagnet to actuate a changeover valve so as to connect the gas chamber of the float chamber to the inner vent when the engine is running, and to the canister when the engine is not running. With this invention, when the negative pressure in the intake manifold decreases while the engine is running at high speeds, the electromagnet keeps the valve from being moved by the spring force and maintains the valve at a position such that the vapor fuel is supplied to the intake manifold through the inner vent.
