Hello though I would bring you up to date with this problem. While waiting for the new spring to arrive I decided to start again and strip the gun right down. Cleaned everything properly, on looking at the exhaust valve seat I noticed that there was a mark across the seat about 1/16" wide and ....

Hi thank you, I do have a can of leak detector, getting old and slow and just didn't think about it and tie it together. If there is a leak then this will find it.

Hello all. I have a problem and that is the ft-lbs has dropped, originally set to 11.5 but I reduced it to 11.2 as this was a good compromise power and pellet count. Noticed that the power was varying and was at 10.2 ft-lbs. Easy I thought put a turn on the main spring screw, not so, managed to set ...

OK chaps, thanks to Julian all sorted now.
Cheers.
