Would anyone know the thread size for the negative stop screw by any chance? Thinking I can borrow a tap/die and clean it up if I could find out the size.
That is the plan mate, however I want to remove the screw first to see if I can clean it up as I do not think it will screw in by the looks of it. May just buy a new screw, nut, o ring but then I have to wait another ? Amount of time for parts.
