Is this the manual you have? https://www.splash.co.nz/content/SR-1 Second Stage 08.pdf

The adjustment procedure is on pages 139-144.

If this is done correctly and you still have a problem, perhaps something in the lever is bent. Was this is a working reg that you serviced or did it come to you with this problem?

Yes, that’s the manual I have. It came this way, if I turn the knob in a couple of times, it works perfectly. But with it fully counter clockwise, I have low OE. Puzzling.

I'm not understanding the problem. That's what the adjustment knob is for.

The problem is that turning in the knob also covers the asperator hole, that’s the predive setting.

.5 with the knob fully out is below spec. From what I read.

Have you adjusted the micro adjuster under the knob?

Yes turned all the way clockwise.

Yes turned all the way clockwise.

Are you sure it turns? They bind up easily and strip the hex pretty easily.
And the hose side adjuster?

Good idea… I’ll take the barrel apart and see if it’s truly turning.
