How to adjust the pressure of oil-to-gas reducing valve

The adjustment method of the pressure reducing valve from oil to gas is as follows: 1. First, adjust the adjusting nut in the middle of the hose connecting the pressure reducer and the throttle valve to the lowest, and enlarge it for 3 turns; 2, then hit the car, burn gasoline, listen to the engine sound to judge the power, if you can't judge, listen to the sound when burning engine oil, basically the same as the sound of burning engine oil; 3. Finally, adjust the idle screw until the idle speed is stable. It is basically enough to test the road by yourself and debug it back and forth.
