Nothing overly major. I was wondering why I couldn't get the valve port/ grub screw hole to line up where they should, the valve just wouldn't push in far enough. Turns out unlike most (or so I thought but I'd stand corrected) mk2's mine doesn't have the recess for the oring (the small one on the valve tail).
Which isn't the end of the world, I'm guessing I can just remove that oring from the valve and It might seal anyway.
It's not sealing. Yet. Although that was trying to fill from empty via the quickfill. I'm going to try tonight filling the bottle then screwing it on to see if a good blast of air will seat everything a bit better.
Edited just to say that screwing on a pressurised bottle did the trick and all is well once more!
