The DRS is developed for supplying ideal air-fuel mixture as pilots desire. A fuel tank is pressurized by the pressure from the nipple in the back plate via one-way valve so that the fuel is pumped to the regulator. The regulator picks up the negative pressure created in the venturi and supplies fuel consistently by controlling check valve according to carburetor opening. The carburetor is equipped with two needles to adjust middle and high speed precisely.
