Gents,
Spent a fantastic afternoon plinking and teaching my little brother to shoot with the above rifle.
I bought it new in 2005-2006 and it's had about a tin of pellets through it since.
I put it over the chronograph out of curiousity and found that it producing a mighty 6.8 ft/lbs on average.
Is this about right for these rifles or has the spring become knackered in storage?
I have never stored it cocked.
Can I simply drop a new spring in or is it worth getting one of these tuning kits I've seen advertised?
TIA,

Get a kit, it will probably need new washers and seals as well if it has never been serviced!
A Webley Longbow in fine fettle is more than capable of producing output power up to the legal limit, so there is definitely something amiss with your particular rifle.

Thanks lads.
The manual seems to have become lost in the mists of time, is there a guide to stripping it on 'tinternet?

does it make a loud mechanical 'clack' on firing? if so, chances are its the piston seel.

Here you go Amir!

Look after that Longbow, if it's a Birmingham made one, it's a classic and there won't be any more...
Good luck with it!
If you want to tune it on the cheap, piston seal from maccari in the US, POK! on here for the spring (if original spring is good then re-use), send the lot to someone like UK Neil for spring guides / top hat & to button the piston / size the piston seal.

Thank you Rob.
Mine is a Birmingham made one, though unfortunately only with a beech stock that has picked up a cabinet dings over the years.
The bluing and metal is very nice, even compared to a centrefire. I saw a Turkish made one at the gunshop when we went in to buy some pellets and it didn't seem as well made.
That manual appears to be for the Turkish Longbow, is the rifle still basically the same?
Is this the Maccari kit you're referring to? http://www.airrifleheadquarters.com/...488/582397.htm
What sort of damage would we be talking about for a tune by, well I don't know who but say UKneil for the sake of argument? If it's a job better left to an expert then I will consider it.
This sounds like the sort of thing I don't want to be doing, I don't have a lathe to bush it and re-drill if I get it wrong the first time.

you need to open the transfer port up to around 3.2mm, polish it, then size a new piston seal correctly and you should see 11 easy.
I have a Turkish Longbow and went as far as increasing the stroke by 3mm and moving to an Oring piston seal....was MUCH better after I did this with setting the power tight where I wanted it much easier.
I'm a tit, 6.8 ft/lbs not fps....
