I need to mess with the LPR, regulator (CP), and dwell. Here is where I need some minor help...
The LPR was taken apart and cleaned. The CP reg will be taken apart, cleaned, new o rings, and lube. What direction do I turn the LPR cap so it has the lowest pressure? This is for the Smart Parts brand LPR; maybe what is called a mini-flo LPR. I dont want to damage my gun when I air it up.
If anyone knows about the CP reg, I have the same question. If I turned the screw all the way in, tighten it, is that the direction for lowest pressure?
On your CP Reg, turning the allen screw clockwise (in) restricts airflow and decreases pressure.
I honestly don't remember which direction to turn the LPR for adjustments. I was told years ago to screw it all the way in and the back it out about 2 turns. Once there, you should be able to fiddle with it to find your desired results.
It sounds like you've got a pretty good handle on what you need to do. Just fiddle with the three factors (HPR, LPR, Dwell) until you find what works.
After thinking about it, I would guess you need more air pressure in your marker (and maybe lower dwell) due to your inconsistent FPS. It sounds like the marker is getting starved for air or something. It's hard to say at this point but I'm just throwing it out there.
