having a problem adjusting the operating lever on my overdrive.  using the manual setting cannot get the ball to lift off the seat with the solenoid energized.  doing research i found two articles that state how to adjust the rise of the ball.  one article states that it must rise 5/64ths.  the other states it must rise 3/64ths.  need some guidance on what is correct.  TIA.
