A carburetor utilizing an acceleration pump, acting in conjunction with the throttle valve, to supply fuel through an injection channel to the fuel-air mixture chamber. A fuel accumulator contains a diaphragm under bias forming a diaphragm chamber of predetermined volume connected to the injection channel by a branch channel, a portion of the fuel supplied by the acceleration pump being diverted to the diaphragm chamber against the bias. The diverted fuel is fed to the fuel-air mixture chamber when the bias exceeds the pressure from the pump and the proportion of fuel diverted is controlled by the relative sizes of the open areas in restrictors positioned in the outlet of the injection channel into the fuel-air mixture chamber and of the branch channel into the diaphragm chamber, the strength of the bias and the maximum deformation of the diaphragm being adjustable.
