Right got it stripped down and it needs a new piston washer. Thanks to Mr Knibbs, that is on order.

Now I need more help, mainly with how to get out seized stripped screws.....

Looks like some in the past has tried to adjust the trigger and forgot that it has a locking screw on the other side (This rifle has the three holes about the trigger) and has stripped the damn thing. I tried to have a go at loosening the lock screw but that is seized and stripped to.

I can get replacement screws but I cant get the damn things off and it looks a mess.

So anyone got any tips on getting them out without damaging the trigger block?

Cheers.

All is good, with a punch, hammer, elbow grease and a whole lot of swearing, the trigger adj and lock screws are out!

Ill upload some images, quite proud of myself that I got them out without damaging anything. These screws have probably never been out!

Well done!

Swearing usually helps!!

Ok so after putting the gun back together and replacing the piston washer with one from John Knibbs. The gun no longer shoots.

It cocks fine but when I pull the trigger it makes a "phutt" sound and I can see the piston just move slowly up the cylinder.

My guess is that the piston seal is wrong and is letting air past.

Thats not all, the trigger adjust and lock screw I ordered from Knibbs are longer than the original and so wont screw in correctly, I can file these down but still, kind of annoying.

So on that note, where can i get a proper leather piston seal for a BSA Club Special? (I believe its the same as the standards)

Cheers

Ah now that I think about it, it was probably may fault.

This piston would not go into the cylinder and so I tried my best are shaving a tiny bit of material off the washer.........opps

Let that be a lesson learned not to do work when tired.

Anyone have any tips on getting the washer to fit right? (I have bought a new one from knibbs)

Nothing wrong with that,the leather seals do need sizing for a nice sliding fit.

A piece of 320 production paper worked well in a Mk1 Meteor.

Followed by lubrication with sunflower oil,yes I know,combustible .
