My new G250Vs and ramblings

[Open Ocean Diver]

I did a spring compression test a while back, comparing both 216 and 218 and I saw very little difference from the ones I have.

Yeah, tried the same but was unable to discern a noticeable difference.

In case it's not obvious, does anyone have any idea why these are not going into violent free flow with viva on max? Any trouble shooting I can do? Or is this the new norm? Thanks in advance.

 

[buddhasummer]

I do know there was a case production alteration but am unsure from when, it was recent though. Maybe it's on purpose?

 

[buddhasummer]

Re no free flow, any ideas? I need a guru. Is it possible the spring could be the cause? Cheers.

 

[buddhasummer]

It bothers me not knowing the why. Bat sh.t crazy.

I hope we'll find out, as a deeper understanding of these differences may help us fine tune all sorts of regulators...

Yes, that is possible. But not having one I cannot experiment.

Is the IP within range? (135 +/- 10 psi)
Have you set the cracking effort toward the bottom end (1.0")
Have you attached the low pressure hose directly to the air barrel, i.e. no tool or elbow in between?
Is the cutout in the flow vane pointing toward the mouthpiece? (It should)
Is it in the VIVA position? (It should be.)
Is the adjustment knob all the way out? (It should be.)
Did the balance chamber pass the bounce test?

If all of the above is OK, then you'll have to start swapping parts out one by one. You mentioned the spring-that might be a good place to start. Next the lever.

I need a guru.

Umm....that would be you!

Have you swapped springs yet?
