Funny thing is I tried to buy a smaller o-ring so I could stretch it and make it thinner if I needed to but they did not have the size.
buy a hand full of different sizes for next time

"So I ended up drilling my stock VS out to a letter B drill which is 6.10mm and put it back in."
Big difference between these two holes! 6mm and 6.5mm. I used a hand drill to spin the valve seat while I used chainsaw file to open up the hole to the size I wanted. Also polished the sharp inside edges so the valve seal didn't eat into the valve seat.
Well picked up some 7x1mm o-rings and they did not fit but at least I have 60 of them. ;^). I measured the o-ring slot the depth is perfect but the width is 1.40mm the original is 1.60mm wide so that's why the o-rings don't fit. Grrr... Looks like more garbage from eBay. Maybe I can stretch a 6x1.5mm to fit? Or drill out my stock vs to? and be done with it? If not I will need a new one from elsewhere.
So I ended up drilling my stock VS out to a letter B drill which is 6.10mm and put it back in. After all that drama and $ spent on no good VS parts and O-rings, I will probly never use, the gun is back together with no leaks. I will have to see what the chrony says to know if all this was worth the trouble but my guess is it was.

You need to find the correct oring, that´s all. 7*1 do not make a seal?, if is too deep try more combinations is just about to find the right oring ... try O-ring 6,35 x 1,27 NBR 70 that has worked fine when the groove is a bit deep. Or get several sizes. oringsandmore o theoringstore is a very simple thing really.
