Curious, what was your "I fixed that" ?
Thanks guys, loving this thread.
I followed the SM, readjusted the orifice and then used the Micro-Adjust to fine tune the spring force. I set both to 1.1 inches with a Magnehelic. Edit to add, with a G250 I root through my sparsely populated spring box for the perfect spring since there is no MA.
So this evening I removed the Air tube from reg-1 (free flow reg) and installed into the case that wouldn’t free flow reg-2… same air tube same parts no surprise reg-2 free flowed.
Next I rebuilt reg-2‘s original air tube with new poppet, O-rings, soft seat. déjà vu reg-2 still won’t free flow.

Both crack at .8 knob fully out.
Measured poppet separation .47 mm, +/- .05 mm.
Scratching my head, with almost identical poppet separation why one goes into free flow and the other will not.
Could it be some small difference in the air barrel, or the Viva vane?

Obviously there must be a difference. Given free flow barrel will free flow in both cases I'm a bit stumped.
I assume you've compared both barrels and both flow vanes? And they appear identical?
This is important, does non free flow barrel free flow in free flow case?

TBH I don't think this affects performance at all but I sure do want to know why this is or isn't happening
I haven’t tried that yet.

Unless it's a combination of variances in flow vane and barrel you'd think it's the barrel.
Questions in my post #156 remain
What happens if you use all parts from free flow barrel into non FFB and vice versa?

Yes, just curious. No, they dive great..TBH I don't think this affects performance at all but I sure do want to know why this is or isn't happening
