Thanks for that 7mmsaum, being such a nasty day up here I have done some research and its quite common for shimanos, I checked the drag washer assembly which was fine and as it came from the factory.
So I greased the rubber seal behind the drag knob...apparently this gets dry ( it was ) and creates more friction than the drag washers and subsequently tightens up the drag knob.
Heres to not losing more good snapper.
Cheers
