Back i the early days of snowmobiling that was the case with all 2T engines.

Gradually the makers have switched us to the electrode that covers the centre. It helped by not fouling the plug, maybe this was because of the lousy oils back in the day. You could grind the electrode back to the side and see if you get any different results. We ended up using platnium plugs to get away from fouling.
