has anybody ever come across the same problem I'm encountering with my super fire 2 torch at all. When I screw a gas bottle on to it the gas hisses out of the little pin hole centre of the trigger body. Had it apart and messed about with it but nothing seems untoward. Cheers to anyone that can help, don't really fancy buying another one but I'm getting a bit fed up of using the quick fire now it's just not the same
