Default Are the factory style Turbo 400 modulators adjustable?

Are the factory style Turbo 400 vacuum modulators adjustable? Looks like there is a screw on the end in the picture attached. Any thoughts about turning the screw clockwise or counter-clockwise and what effects it would have? Thanks, Jimmy
