I tried pressurizing it again and found the screw holes leaking even though
the cavities are darn near filled.  I am amazed how the air can find it's
way out.

I intend to start all over by removing all coatings and open the screws up
the 1/4 - 28, alodine everything and follow the procedure again.

I found a way to build a split clamp to hold the slide throttle independant
form the seal plate

If you don't fill the cavities you can get to the
back side of the screws with conformal coating.
Pressure will force the conformal coating
into the area around the threads if you
pressurize it quick enough. If it don't
work the first time you can do it again.

Forget filling the cavity with epoxy we learned
along time ago it does not work very well.
