they are quite easy to work on.. just ask a specific question on here...

[WebleyWombler]

Yes quite easy to work on. What's the problem that it needs help?

[jedburgh]

Sudden loss of power , pellets won't leave the barrel .Air leakage at the breech , leather washer good .Still requires the same effort to cock it .i wondered if it could be the piston ring .

[WebleyWombler]

If air is leaking at the breech, that would be the first thing to investigate. Can you carefully prise out the fibre breech washer and pack it at the rear with a steel washer as a trial ?

Once you have done that, do you have a chronograph to test it with?

[jedburgh]

Thanks for the tips .Will take it to bits tomorrow and have a look .

If the breech lock lever goes al the way over and touches the action without tightening up, then the breech washer either needs packing, as suggested above, or replacing.
I'm sending you a strip guide by email.

[Phil Russell]

No harm in having another strip guide ... try Collectables, Idiots Guide post 167.

Don't jump in too soon. Sounds to me like it needs the breech washer sorting and a bit of cylinder lubrication with some nice thick SAE 30 motor oil (Webley themselves used to state the biggest cause of poor performance was lubricating the cylinder with too thin an oil) 3 in 1 or WD40 will kill it very quickly.

[Phil Russell]

Take not of the above re lubrication. When I first had a MK2 I thought I would treat it to a service ... complete clean and relube with 'modern' materials. The end result was awful ... power was quite down. Then I read about engine oil being used. I cleaned it up again and used the engine oil ... result! All back to how it should be.

I believe you can use O ring for the piston but have not done this myself. But I have replaced the piston rings on an Osprey with an O rings to good effect.

Standard Webley lubricating oil of the period was SAE30.

Which is exactly what it was ! Washer was cracked .Replaced it with a tap washer , worked a treat .
I am glad I stripped it down , was able to clean and oil it .
Many thanks to all who helped .
