Daystate DAYSTATE REGAL REGULATOR ISSUE

[SilentSquirrel]

Hello members
I just picked up a used 22 caliber Daystate Huntsman Revere.
It appears to be in excellent shape
Upon arrival it was holding 200Bar and the regulator gauge showed 180 Bar
At first, I thought this meant that the regulator was set very high
However, as I test fired the gun the regulator pressure gauge decreased in direct relationship to the tube pressure, and increased when I topped up the tank
Daystate gauges have very few numbers, but here are some imprecise examples of the situation.
Tank 250Bar = Reg gauge 225Bar
Tank 200Bar = Reg gauge 175Bar
Tank 175 Bar =Reg gauge 150Bar

The questions are
What's causing this?
And where do I begin fixing it?

Thanks in advance
Edward

Your first move should be a call to AOA and ask questions. If I were to take a wild guess, it's adjusted out of its design range and can't control pressure.

Here's an update
Albeit a long time coming
I spoke with Shane (sp?) at AOA
He agreed that the issue was most likely that the regulator was set too high.
And also said that even though the rifle was filled with air but not been shot for over a year, damage to the regulator was unlikely.
So, armed with the excellent Daystate Workshop Video I dove in.
I removed the regulator to find that there were no markings for pressure on it
I took measurements as per the video, marked the current setting and opened it up to inspect the bellville washers.
The washers were correctly oriented.
This procedure did not change the current setting.
I then tested it on a Huma regulator tester
To my surprise, it was set at 140B
This is way under the reading & behavior it was exhibiting.
I reset it at 150B on the tester
Once reinstalled I filled the tube and the regulator gauge on the gun matched the test at 150B
It is now shooting consistently at 150B
No more falling off the cliff

Considering that I did nothing other than inspect the regulator's innards it is my opinion that the bellvilles had taken a set over time and the degassing and inspecting freed them up

That's my story and I'm stickin' to it
