I pulled the plugs out, they were the ones that
came from Atkins, these plugs looked new on the outside, but were used to keep
dirt out of engine, as they were used and plugged full of carbon. The
plugs are NGK T-SD 11A; L-SD 10A. I see where Lynn and AL are using
NKG R6725-11.5's, Is this plug used as a leading and trailing plug? At any
rate, I need to get some new plugs. JohnD
