Well guys,
Plenty of answers to my question, obviously not as simple as expected to find or cure the problem !!!
Easiest way seems to be is to get a " shoot thru hull " type as i dont really want to brak seal on old one, any suggestions where i could get one at reasonable cost?
Thanks again for all your help gents,
Tony, I wouldnt mind seeing your set up when your available.
