Welcome phill uk,
Wuputt (US) would be the man to talk to about fixing the leak, phill uk, he rebuilds them and has a couple rebuilt spares sitting just waiting to swap with members I think, you send him yours for him to fix and he sends you an already rebuilt one. Not much down time.
There are a quite a few members from the UK here, acp (bristol), monkeyhanger, Blagada'n (ireland) to name only a few, there are so many UK members that are active posters here it's hard to keep up, so have a look around in the latest threads in each section, you're bound to come across most of them eventually.
Mick "Stormy' Cole,
New South Wales, Australia.
BTW, fill out your location details in your "usercp" and the others will probably contact you...
