This screw regulates the idle air. If it is too wide open, the mixture becomes lean when accelerating. Then the engine stops most. If the screw is closed too far, the engine sputters and there is dark smoke from the exhaust.
  4. The second adjusting screw, which is sometimes indicated by a H, regulates the mixing ratio of air and fuel. This screw should then either something in or out turning. You should do until the engine runs smoothly and leaves no more smoke from the exhaust.
