David, I appreciate your time and experience. I hope it is clear, that I
am not being argumentative, but I am just exasperated. Are you familiar
with the point in such repairs where you either have to sit and cry, or
toss something very expensive, against the wall? :-) I am there.... Its
a brain clog, and until I get past it, I can't continue, so I am
soliciting all that I can get.

When you say that if I turn the screw, it won't open the valve, yet is
surely does, as the leak test shows that with zero lash, I am fine, but
half a turn in, and the valve pushes open, and the test is a
failure..... I have the clyinder pumped to 90psi, it leaks down to 80psi
with zero lash. Half a turn down, and the leak goes to 20psi which I
guess means I opened the valve <shrug> Since I think you are right, and
I am blanking out, any way to explain what I am seeing?

As I tell everyone right now, I am stuck, and would like a push, in any
direction would be fine <g>

Thanks very much,

John
