Unfortunately you seem to have failed to change the o-ring most likely to be causing the problem: the o-ring on your Inline Regulator Pistonmy ego 08 reg leaks from the apature half way up the main body of the regulator. so fai i have:
-cleaned the reg
-changed all the orings (top of reg, inline adjuster screw x2, swivel collarx2)
otherwise the marker is fine, when i change a reg its consitent accurate and all that jazz so i think it is purley a reg problem...however I am open to suggestions.
