Hi.
I've recently bought a Diana model 60, it shoots very smoothly but the cylinder end cap has no locking screw & the hole for the locking screw is nearly 180 degrees out (at top instead of the bottom).
I've just taken the cylinder end cap off to have a look & the rear piston is practically flush with the end of the cylinder where I believe it should be set back around 0.3mm?
There is the stepped spacer inside the end cap but no shims behind it and the step was facing the inside of the cap and not (as I would imagine it should be) facing into the cylinder.
I'm guessing the step in the spacer should fit into the end of the cylinder but on mine it tightens up against the end of the rear piston before the cap is screwed all the way home.
Any advice where to go from here?
Thanks.
Neil.
