I don't think this is in any of the books I have.  It would be nice if it was there.

JB;
        I had the same problem. There is a small adjustment bolt through
the body of my valve unit. If memory serves me, I sighted though the unit
and adjusted for the most light shining through the opening. Make sense?

Good Luck and Drive Safely
