LeadTurn_SD: I did apply a correction factor that deals with the air pressure and density at the respectable altitude of 332m/1089ft in Geneva

awap: I'll go over my instrumentation and methodology and report back if I did something wrong.

Edit:
I checked the Repair Guides for the G250HP & the S600-550, and the recommended cracking range is 1.0 to 1.4". Maybe the 1.25" CGF in Pete's book is for a different or a generic reg?

One other thing to consider is that your user adjustment knob on a 250 should easily compensate with just a fraction of a turn.

Some explanation may lie in the accuracy of your magnehelic...

I don't have a magnehelic; I used the water method, accuracy is probably 1st digit and order of magnitude.

So I hacked together a quick & dirty manometer, and guess what: 18mm/.71". Accuracy is now a lot better, and, because it's a differential mesurement, it's self compensating for the altitude of Geneva.

The sample I mesured is my #2 son's G250C; it has 17 dives since I serviced it last winter, and not a single case of free flow that I know.

That's great, but all I can say is that if I lived in Geneva, I'd spend all my time hiking and skiing, and not working on regulators!

A typical sunday morning conversation deep in the heart of the winter:

Me: "Let's go skiing!"
Kids: "Is the powder fresh?"
Me: "Not really, it's from the day before yesterday"
Kids: "We're not going"​

Spoiled brats.

Any vacancies in the Geneva Jazz Quartet?

Not that I know of, but we can put a band together and make some platinum records!

Records!! RECORDS!!!! Damn, we must be old.

....Speak for yourself. My records are disc shaped, not cylindrical.

Manometer tip: A few drops of food coloring in the water makes the manometer a lot easier to read.
