Abstract
A carburetor with a fuel compensation device have an exhaust gas recirculation passage with an exhaust gas recirculation valve, as that an exhaust gas from an engine may flow into a suction passage through the exhaust recirculation passage. The exhaust gas recirculation valve comprises a diaphragm, and controls the exhaust gas flow recirculating in response to vacuum during the recirculation of the exhaust gas. The vacuum is taken in from a vacuum intake port defined in the suction passage, the position of which is disposed slightly upstream of the position of a throttle valve at which idling of the engine is effected. At the same position as that of the vacuum intake port with respect to the fluid flow direction in the suction passage, there defined is an auxiary fuel jet port communicating with a float chamber, so that fuel is jetted into the suction passage corresponding to the quantity of the exhaust gas recirculating.
