Reply To: Kg7 stripped spark plug hole.

Not that I can add anything useful to the subject, but, I do wonder why welding in some material to machine and tap a new thread is not done. From what little I know of old outboards welding gas tanks, crankcase, clamps, towers, props were commonly done along with machining as required. Would someone who knows care to comment on pros and cons of the subject?
