Tuning Stuck in low first reg Pressure

[Esab]

Today I decided to change the second reg washers stack to improve the slow recovery time. So I did. I drained the air and I noticed air escaping from the front as soon I removed the bottle but the plenum still in pressure. I shoot few times to drain the plenum pressure and I started the procedure to get 200 bar from the first reg and 165 bar from the second reg as was before. I don’t get more than 140 bar, no matter what… I’ve tried to change washers tickness few times but no success. I bet it must be a leak but I can not figure it out where.
The gun is a wildcat mk3 bt sniper in .25
Hope I made my self clear enough
Any help?

Did you loosen the adjuster screw is it a amp reg lossen the small set screw for more pressure tighten for less pressure

 

[Airgunmann]

Snap a picture of it I'll try to help

 

[Esab]

Yeah man, I did it few times and I know the right procedure. I own two wildcats
But Thanks!
The days before was working flawlessly and I can’t figure out what went wrong

 

[Airgunmann]

Just a dumb question you have more than a 140 bar in you filling tank just trying to think of a simple thing that could be wrong

 

[Esab]

Both regs have been mirror polished
and resealed 2 weeks ago
Only the recovery rate was a bit slow, that’s why I decided to take them apart to try less ticker washers

Yep

 

[Airgunmann]

Or possibly the gauge is bad or blocked ?

 

[Airgunmann]

Yeah I mean not a lot to them different washer stacks will change pressure like you said

Tried switching 6 wika gauges, is not enough? I also tried a brand new one which came from krale 1 week ago

I don't know sounds like you got most of the bases covered do they have the brass piston in them ?

Yes

I guess it could be a leak but you think if it won't let you get a ove 140 you would hear it I've had the gauges to tight on my impact a couple times where it seemed like the plenum was filling slower than it should but loosened them up a tad and the gauge would jump up to pressure faster then

 

[Esab]

I do no think is the case but I wil pay more attention tomorrow

I had to trim the length of the brass piston down on my friends M3 impact it was to long and couldn't get up to the pressure of 200 bar the cap was turning the set screw in as the bottle was being turned on I shortened the piston some and removed the adjuster and shortened it so it would stay off of the little cap that goes into the front of the reg on the M3 maybe it's adjusted right but when you you screw the bottle down it's turning the adjustment screw back to less pressure idk a problem I had with front reg I'm not sure exactly how it's set up on the wildcat

I do not have a clue, yesterday was working almost flawlessly

 

[Airgunmann]

It's frustrating when stuff like that happens

 

[Esab]

All sorted! Nothing wrong with the rifle. It was the second reg adjustment screw: it was flush with the reg body but still blocking the air from the first reg. unscrewing the adjustment screw a tiny bit more made the pressure where I wanted!
