Yes that's the way to set them up but I meant how much preload on the spring that closes the firing valve? is it still at the factory setting?

I set it so the transfer port is fully open i.e the screw is flush on the inside of the transfer port so no restriction.
I then set the hammer to about 770fps this has always given good consistency and shot count around 80 shots.

Simon whats the benifits of restricting the transfer port on a regged S200?

You will find if you set it to 800 on the hammer with a wide open port and then trim it to 785 ish on the screw it will tighten the consistency a little with no loss of shot count.

Cheers Simon, when i came to see you a couple of years ago for you to service the reg you said it was your original design so id say the MK1 reg.

problem im having is when i go over 775fps(8.44gn) or higher it gets even worse accuracy goes to hell, gun kicks more so ive always set the hammer to 760-770fps, reg works superb very consistent over the chrono.
The only thing i can think of is the plenum needs more capacity?

You could turn the reg up a little, it is possible the output pressure has changed since it was set, try turning the brass adjuster 5 minutes anti clockwise, which would be unscrewing it. By your description of its behaviour I would say the setting has gone a little low.
