Re that cylinder.....yep, give it a light polishing as you mentioned with the Solvol. Never forget that, in the dark, distant past (), some exponents of spring gun tuning actually tried to achieve a cross-hatched, slightly roughened, finish to hold lube (a) for lubrication and, (b) to give a source of fuel to promote controlled dieselling. Long behind us now.

I'd try and polish as best you can and then, if you don't have any already, buff some moly powder, moly paste or moly from a spray into the cylinder surface. Then buff it again. Then the tiniest of smears of moly paste onto the edge of the piston seal, any acetal rings and the rear bearing portion of the piston. And then, as previously mentioned, once the piston is inserted and pushed fully forwards, a helping of moly grease around the circumference of the cylinder, behind the piston. Should help with smoothness and to ward off, hopefully, any future wear.

It's got the cross hatch honing with even more aggressive scouring over the top Looks like I've not got a piston coming after all.


Knibbs has got one for 40 quid, but with postage & having to post my old one to them it's not going to that much more expensive to buy the fancy one off Alistair


I'm wondering if a spot of weld on the end of the trigger sear that doesn't engage the piston latch would make the piston latch end sit higher & engage the latch, thus saving me a few quid on this hopelessly over budget swamp donkey.

It's enough to drive a chap to drink.
