Why do many diagrams on this topic display the valve lag and lead near BDC as valve overlap as well when it isn't? Ie. between ur top red and green line they are shaded as valve overlap, correctly, but then also between the bottom red and green line also. I have found this on google diagrams and in a book I have on engines, makes no sense but there must be a reason.
is more overlap the culprit for the lopey idle?
