I have not long brought a cp88 that was shooting ok then when I went to change the gas it was pissing out everywhere, I tried all the techniques to inserting a bulb but nothing would work so decided to strip it down and see what was up.

Anyway the valve seal looks ok no nicks or nothing and wonder wether its worth changing it now or just rebuild it after a clean? Can you buy seals online do you know please?

Also does anyone have a strip down guide either online or one you have done diy please as it would be very much apprechiated.

One other question I have ended up woth 2 small ball bearings and i`m unsure where they came from bit but pretty sure its something to do with the slide release?

Any help much apprechiated or someone local to Coventry to show me what to do. Thanks.
