Hatsan Is my new Hatsan regulator broken?

Thank you for taking the time to break that down for me.Okay, got it...yeah it sounds like our terminology is getting crossed up. People typically use the phrase “all the way in” to describe the hammer spring being maximally compressed. But since you have tried moving it the opposite direction and found the shot count to get even worse, it sounds like your original setting was indeed at the minimum.
What we don’t know is whether this minimum setting is optimal for the new regulated pressure. When it was unregulated, you indicated it was working well over a pressure range of 200 bar down to 100 bar. What this would mean is, unless the regulator is set quite high—something north of 150 bar—the hammer strike is now too much and it is wasting air. This is a trivial thing to see with a chronograph by making slight adjustments to the hammer spring tension and checking to see if the velocity rises, falls, or stays the same.
Then what you want to do is find the maximum attainable velocity, and finish by reducing the hammer spring tension until the velocity falls just a little to about 95-97% of the maximum you found. When adjusted in this manner, it will use air efficiently and produce a stable velocity.
In the event there is not a sufficient range of adjustment to either go high enough to reach the plateau (max velocity) or low enough to see the velocity begin to fall, it signals the decision will need to be made to either alter the hammer spring (add spacers to increase preload, or shorten the spring to reduce preload, respectively), or change the regulator setpoint.
I guess I will make a chrono my next must have item.
Thanks again
