massive reconfiguration time again.

So sorry to change the subject to my massive configuration LOL, but I pulled a couple plugs and they seemed to look ok? Again I've been watching my air-fuel and it seems to be idling now where I want it at about 14.7 to 15... I'll be damned if all the times I punched it yesterday on those country roads I didn't look down once at a/f Gage....

this don't look right. Could be just the picture. Is the ground electrode not over the electrode?? I like the porcelain (insulator nose) to be cardboard brown.
