Hi, let me preface this by saying i don't know diddly about the Artemis regulators or the gun for that matter, I'm sure there is someone on this forum that does. Have you done a search? Does the gun hold pressure over night? If yes than skip any leaks in the reg. If No then a bad o-ring, always a good idea to change them out anyway. I see that they don't have a breather hole so, you'd have to balloon the barrel, probe closed. Side note, I see that Lane and Huma both make regs for it. How about the breech o-ring, I'm assuming there is one, is it good?

I your NOT losing pressure as in a leak ?
And what ever tank pressure is, also is the plenum pressure ?
You have #1 a failed o-ring on the seat height adjuster if one in present in the regs design.
That or debris on .... or just a damaged seat sealing surface

sounds like the regulator was stuck open,,, your tear down and cleaning must have freed it up,,, nothing like SPA/Artemis QC
if it happens again, ya might want to polish the belleville washers and like Scott said,,, seat sealing surfaces

Pretty sure our buddy Jack nailed it. What kind of lube are you using on it? Personally I like synthetic motor oil, it's slick. Just a VERY light coat on your fingers then rub everything or a bit on a clean microfiber towel. I prefer my fingers, you can feel imperfections.

Yeah, that .... if it moves 90, if it doesn't , 70. As I stated I use Synthetic motor oil, not a fan of silicon. I've done the regs in both of my Mavericks and it's been longer than I can remember, still working great. NOTE: If the o-ring that requires a 90 is SMALL, chuck it in boiling water, that'll soften it up and let you get it on instead of breaking it. It won't hurt it. You'll need some pointy tweezers to handle them. The Maverick has some really tiny ones (2x1), a total PIA but the method works.

Yep, great guy, knows a lot of stuff, has helped me out greatly on my Sapsan. There are a lot of very knowledgeable people here.

REGULATOR inner spool can not get "Stuck" unless ... 
There is Corrosion / Rust within the interior spaces and on the parts.
Or reg has been unused for so long that the o-rings have hardened and Glued / Adhered themself to the body of the regulator.
*As one who has serviced 100's & hundreds of PCP regulators made from Aluminum, Brass, Steel & some plastics .... they fail for other reasons, but getting stuck or hung up is not one of them if there clean & lightly lubricated.

see Answer #3
Generally if you dismantle an o-ring sealed devise ... reassemble with NEW o-rings
