I have had the above gun for a while at the back of the cabinet.
Dragged it out yesterday for a bit of degrease and polish.
Welsh willy kit fitted - good news.
4 penny pieces as washers in the piston - not good news.
Stripped, cleaned, polished and lubed and I can only coax 5.8 ft.lbs out of it.
Any advice welcome, also can anybody tell me the o ring size in the breach seal set?
Cheers chaps.
