ABSTRACT:
In an air-fuel ratio adjusting system for an internal combustion engine equipped with a carburetor having a bypass air passage for controlling an air-fuel ratio of an air-fuel mixture to be supplied to the engine, a bypass valve disposed in the bypass passage is so arranged as to move during no-load running of the engine at a speed lower than that during the normal running of the engine under the load, thereby to prevent disadvantages such as the engine stall.
