Cream Puff you are a dill.
As an engineer I cant go above or beyond what the manufacture says. So end story.
They say 1 and I go 2 then you have an accident then you sue me then what grounds do I have,
Industry behind a piston engine, well my dad has over 20000 hours is that enough for you, like I said before I wont place a pilot or anyone I wont fly in my self. Never had a problem with a commercial pilot.
Sorry I guess if you have so much time on your hand you do some research on aircraft ignition systems and then learn a bout "E" gap but I guess you already know about that.
