I think that I messed up the timer. After a recent top end we opened the adjusting nut for the powervalve real far until it clicked. that didn't sound right and after screwing it back in it appear that the whole nut is too far out now. In order to get the mark on the actuator arm to line up higher between the marks in the window, the adjusting nut has to be out pretty far. When I screw the cap with the copper washer it bottoms and begins to screw the adjusting nut in. Did I mess up the timer?
