Update:
I got some nylon washers:
7mm OD, 3mm ID, 0.8mm thick.
I managed to mount one retaining the rubber oring underneath it.
Without oring i was getting a puff of air on the face.
My reg is still @ 12:45 (75bar).
As expected i had to increase the hst as i had lost a good 100fps with the choking.
However i can’t get more than 540fps now, as even if i increse the hst further the speed doesn’t increse any more.
That’s a good point, as it is here we wanted to get.
So now i need to re-increase the reg pressure a bit so that i can get a speed of 570.
BUT HOW MUCH SHOULD I INCREASE THE REG PRESSURE?
I recall that you told me that a good situation is when one reaches the wanted speed at a point where even with further hst increase, the speed doesn’t change
I reckon I’m a tad below that point, so the moment is crucial.
Just a reminder for my attempts and then you tell me where to move the reg.

Reg @Stock 12:00 = 130 bar
Reg @ 12:07 = 125 bar 
Reg @ 12:15 (1/4 turn clockwise)= 110 bar
Reg@ 12:45 (3/4 turn clockwise)= 75 bar

Would 80bar be enough to allow me to get 570fps, still keeping the situation that further hst tension would still give me 570fps?
Would 90bar or 100bar more appropriate? (so that the reg has still pressure to let me increase the speed to 580+?
Given we agree for a pressure, where is it in the reg position? (12:30? 12:40?)
Ed, any thoughts? You said you tuned your reg at 100, where should i move the reg screw then to reach 100?
Any advice on how to move forward welcome, i’ll disassemble it tomorrow.
Cheers
