When you had the LPR disassembled - did you get the two balls back in place in the correct order?
Is there any unusual wear on engine components?
I got it working now I think. I replaced every oring in the marker and now the lpr will adjust up to about 100 psi. I am able to get the gun to shoot about 300 fps with correctly bored paint but it wont go any higher. Should it be able to or is that about the max?
I go the gun into chrono range and then turned down the lpr until the velocity started to become affected and then back up just a little and when I checked with my pressure tester, I was right at 80 psi. The hpr seems to have a sweetspot like a cocker at ~200 psi. at 80psi and 200psi with bored paint I can shoot 280 and I can get the gun up to about 300 fps by raising the hpr but then the velocity starts to drop and become extremely in consistent. Is this normal?
The only thing that I did different with the lpr is flip the disk that the bearing push against because one side of it had an indent where the ball was pushing against is and I changed the oring on the piston.
I am happy shooting to velocity with bored paint because that is how I normal have my gun set up but when it gets cold like it is now I dont like to bored my paint as close to help avoid barrel breaks and most other guns have no problems shooting 350+ fps so is it normal for a vic to not have as much adjustment range (like 250 fps-295fps) or not?
