Abstract:
A carburetor, comprising:a body having a fuel and air mixing passage and a separate air passage; a throttle valve received in the body and rotatable between idle and wide open positions and having a throttle valve shaft extending generally transversely through the fuel and air mixing passage with a throttle bore through the shaft; an air valve received in the body and rotatable between fully closed and fully open positions and having an air valve shaft extending generally transversely through the air passage with an air bore through the air valve shaft; and a lost motion coupling selectively connecting the throttle valve and the air valve to permit rotation of the throttle valve relative to the air valve from its idle position to a predetermined position between its idle and wide open positions and to thereafter cause rotation of the air valve in response to rotation of the throttle valve with both the air valve and throttle valve being simultaneously operable in their respective fully open and wide open positions.
