An improved carburetor for vehicle engines of the down draft type having a suction duct connected to an intake manifold, a float chamber storing a predetermined constant quantity of engine fuel and arranged on one side of the suction duct in the transverse direction of a vehicle equipped with the carburetor, and a vertically extending fuel passage connected at one end to the float chamber and at the other end to a main fuel nozzle opening into the suction duct, the carburetor being capable of holding the fuel contained in the fuel passage at all times at a predetermined constant level for highly stabilized fuel supply to the engine irrespective of lateral or longitudinal inclinations of the fuel surface in the float chamber occurring under conditions of acceleration, deceleration or turning of the vehicle. To this end, the float chamber is formed such that the right and left halves of the chamber divided by an imaginary vertical plane through the axis of the fuel passage and which extends longitudinally of the vehicle, are equalized in effective volume to a substantial extent, whereas the front and rear halves of the chamber divided by an imaginary vertical plane through the main fuel nozzle and which extends transversely of the vehicle, are also substantially equalized in effective volume.
