Here's the progression, and in the end I know that I'm the problem....
-Got the gun and things started out great. Ran about 600 pellets through without a hitch.
-Came back a day later and went to fill the gun and it wouldn't take a charge, just running the air out as fast I I put it in.
-Was recommended that I tear it down and replace the oring.
-Did that and while I was at it replaced all of the orings with recommended quality orings and good divers silicone grease. At this time I also polished the trigger parts and restacked the bellville washers to the recommended order.
-go to fill the gun and as I put air in it's leaking straight out the barrel.
-tear down round two.... This time I give everything a good cleaning with the ultrasonic cleaner, rinsed, blew it dry, and reassembled.
-now no leak and I go ahead and shoot the gun once and put it away for the evening.
-This morning go to check that it's mostly holding air, and it is. Go to take some shots and click... No shot! Hammer drops and nothing.
-I assume that this issue has to do with the adjustment of no. 24 and no. 9. I already assumed that I could do this and have made the @@@ of me. No more assuming....
I'm sure this is me and not taking good notes on where all of the factory adjustment of screws and caps should be and I'm at a loss. I'm not going to even give it another attempt until I get some sage advice from this board.
Hopefully you guys can help this novice figure out where I went wrong and I can learn something along the way. I'm feeling like the Forrest Gump quote "Stupid is as stupid does..."

Describing what is #24 and #9 might make it easier to suggest ideas.
I looked at the schematic Wimpanzee posted. Did you say that the pistol is holding air but won't fire? I haven't been into the regulator yet so can't say anything about 24. Hopefully someone else has information that will help there. 9 appears to be the valve spring retaining cup/screw. As long as you screwed it in enough to engage but made sure the valve would fully open then that should not be the problem. I hope you didn't bottom that screw out and coil bind the spring (if that is even possible). If this is what you did then you may have broken the poppet or pushed the valve stem through the poppet body or otherwise damaged the valve. From looking at the valve design itself, the stem that the hammer hits must be able to push in fully flush with the face with pressure you can apply directly (while holding the valve in your hand, not in the pistol). When I had mine apart and put in a different valve spring I simply made sure that I could press the stem in to or below the valve face. If you screwed that cup (9) in too far then you may have coil bound the spring and when the hammer was hitting the valve stem it may have been pounding that stem through the body of the poppet or damaging it in some way.

One part at a time.
#9: you can screw this in so far that the poppet simply cannot open. Push on the hammer with your thumb, does the valve stem move? if yes, the poppet will pass air. Not saying you don't have it adjusted a little to lose or tight, just that the valve CAN open.
#24: this is a more likely culprit. If this is adjusted to lose, the reg won't open. Try tighten it little at a time and see if you can get air to the valve. if it gets hard to turn, and, still no air then something is not right inside the reg.
You mention you restacked the bellvilles, I don't think you can stack them in a way that wouldn't allow the reg to open with enough tension on the nut.
When you had the reg apart, did you notice that part #31 is beveled on one side of the hole? that bevel, is for the bevel on part #32. That white disc can go in either way, BUT, only works one way. If #31 is in backwards, and the needle valve(#32) is screwed in tight, it will never open and pass air.
