OK, I dismantled my 45, fitted new spring and piston seal . Piston was very very tight, managed to relieve that to make it slide better. Assemble it and the disconnect lever gets jammed down. The gun compresses the spring ok but wont cock. I have had the blessed thing apart so many times I am getting a little tits off with it. anyone got any ideas or , better still, know a decent airgun mechanic who knows about these blinking things. I have got to the point where I would rather pay someone to fix it than take it apart myself. I want to shoot it not mess about with it lol.
Obviously some where along the line while it had the cylinder removed something went out of sync. goodness knows what. Looked inside at the sears etc, black magic in there.
