My P2 has never had good speed consistency but recently its got much worse and hit 30FPS spread yesterday. Reg did have bad creep but its now fixed and is not the problem. Set to 156 Bar. The gun has been apart many times but I have never had the valve out until yesterday. Here is what I found.
The spring inside the balance tube had worn itself a trench in the valve end and the aluminum debris had got behind the O ring. Not rocket science that a sharp hardened spring end will ware away aluminum.
I have cleaned up the valve end in a lathe and ground flats on the spring ends. Its probably removed about 0.5mm from the length. Probably not critical.
Not tested yet.
I see that there are at least 2 new valve types after the one I have. I wish RTI (or manufactures in general) would keep owners up to date with issues and mods. They would get huge respect from the community.
