PURPOSE:To stabilize action of a carburetor by arranging a mechanism which links an air control valve opened or closed with negative pressures of a venturi area to a throttle valve and a mechanism opened or closed with the negative pressures of the venturi on one shaft thereby performing opening and closing actions. CONSTITUTION:An air control valve 2 arranged in a venturi area 16 of a carburetor 1 is turned about a shaft 22 by introducing negative pressures of the venturi area via a conduit 17 to diaphragm 18, and turning a 1st lever 21 by means of a rod 19. On the other hand, since a lever 24 fixed to a throttle valve 3 turns via a rod 25 and 2nd lever 26 to move a stopper 28, and 1st lever 21 becomes capable of opening up to a point where it comes into contact with a stopper 28. A stopper 27 gives an opening ratio at the time of start.
