Help me tune this Titan second stage

[BigRed96]

Good Evening Everyone, it’s been an adventure filled day. I rebuilt a first stage Titan regulator, and then this evening I had some free time I dove into the second stage Titan. After running into an issue with the poppet bearing I had to reuse the old one. I put the second stage back together and it works...kind of. The issue I am having is that the diaphragm is fluttering badly when I inhale on the regulator. I can figure out the problem. IP is at 140 psi, and I have the lever and crown adjusted according to the book as far as I can tell. I can post a video if that would help. Pardon my fat belly.

Pretty common with a dry reg. get it nice and wet and give it a try, or if you really want to try it out, stick your face in the tub with it!

All mine flutter/stutter on land, it's quite normal and in itself not indicative of an issue.

Thanks Gentleman, I appreciate the responses. I also asked my Father if the regulator did that before I serviced it and he confirmed that it did. I tuned it to the best of my ability and according to my electronic manometer it cracks around 1.2 in h2o, so it is within the specs. Thanks again!

Ahh the quacking duck second stage.
Like the rest said, it's not uncommon for them to make that noise out of the water, nothing to fix, some just do it.......come to think of it, I have never tried getting it wet then checking to see if it quacked. I need to give that a try.
