Abstract
In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.
