Need Advice Rebuilding LPR

[Knuckle Dragger]

I recently procured a Dark Timmy. The lpr is creeping badly, and I can’t figure the best way to separate the lpr. I think it’s a 2k5.

Got it to open without damaging further. Adjustable wrench and rubber bands for grip.

Fixed the creep issue, replaced orings and new grease. Been plugged in air for a while and pressure didn’t rise. I now need pressure settings. What is the lpr and hpr supposed to be set at?

Found the factory pressure windows:
LPR 70-80 psi
HPR 200-280 psi

Use the lurker method for tuning over a chrono.

1: Back out both regs or Zero out both the LPR and HPR to 0psi
2: Raise HPR slightly only to set LPR for cycling
3: Raise LPR to fully cycling ~45psi or so
4: Raise HPR until velocity begins to stop rising as you increase pressure
5: Raise LPR to desired velocity
6: Lower HPR a bit, then raise if necessary... you're trying to find the best HPR setting at the LPR setting you have. This may put your velocity over 300/285
7: Lower LPR slightly to field velocity
