Which leading edge? Towards #8 or #2 edge on the #1 plug. I always forget. Old age.


Don't worry about leading or trailing edges. Just line everything up point to point and then fire it up and check it. That way you'll know what you are looking at. Once you know what you are looking at you can tweak it.
