FX cant get velocity from FX Crown

[Sharp Pog]

I am hoping that that someone can help me find a solution for my FX Crown Mk11 . I can not get pellets speed much over 700 FPS even with reg up to 160 and settings for high power I recently changed the reg and it was Ok for a short while . It not breech seals because I tried it with 2 different barrels .Any help will be appreciated Thanks

Thanks to all who offer advise for a fix . I was able to get it straighten out . I had to put more tension on the hammer spring with the micro adjuster and then after that it was getting the reg pressure and hammer setting to work in unison. I have the reg set at 145 I was able to tweek out up to 920 FPS using 33/34 grail pellets. I backed it down to about 900 FPS and it was shooting very nice one hole groups I will be using it at the Pyramyd Air Cup shoot .

Glad that you got it sorted out.
145bar seems like it would be about right for that weight pellet and speed.
As stated, at 135bar and using 25.4gr pellets, mine runs right at 920ish FPS.
