The screw on top adjusts how much the aneroid restricts the fuel. The star wheel adjusts the pressure at which it kicks in. Really all you need to do is screw the top screw down as far as it it will go, or as far as it takes to make the sky as dark as you want it...don't have to mess with the star wheel.
The aneroid is nothing but an emission control device.
