will dig out the info and send over with vernier reading as well on dimensions. My current mod uses plumbing parts, so i chose a spring that fitted those, but also tried larger/wider that would fit inside the stock. The amount of preload (produced by the short piece of plastic pipe, though could just as easily be a bit of stick!) is demonstrated in a pic which shows you how much of the weight protruded from the stock end before the brass retainer piece was fitted - but because you are dealing with a 'squiggier' longer spring, nothing is really critical and easy to adjust with trial and error.

hi,great write up ,thanks for sharing.i have the same model but single shot in .177.the only significant modification i have made to mine is to fit a concealed trigger sear engagement screw,makes for a much improved and lighter trigger pull. i havent used my gun in a while and was thinking of selling it but may now use it as my interest has been re-invigorated by this thread,cheers greasemonkey..

Thanks for the info, just turning up a new exhaust valve for one of these. They are just plain nylon and tend to crack and leak with all the impacts on firing. When you strip them looks like someone made them up as a home project, but good performers and very accurate.

Post a PIC please. Do you mean the exhaust valve on the air cylinder? Cheers, Richard

Richard, yes the valve hit by the hammer on firing. This rifle is not mine and is back with its owner so I have no pic, but I am going to make another valve the week after Christmas so will take some then.

Thanks baz - .Would greatly appreciate it if you can squeeze some pics onto the thread as suggested when you do the next exhaust valve 'repair' as would be good to have all the references in one place....
.... But mainly because I would like to see and know how to deal with any similar future problem on my gun.

Seasons greeting s to all who chance this way in the meantime!!!!

How do you get that valve assembly apart? I got one of these guns last year and it looks like the firing valve assembly has developed a problem. I've had the assembly out of the air cylinder, but couldn't work out how to disassemble it further.
