I peeked into the spark plug holes with a bore scope. Not the best bore scope, not great on close up, hence the fuzz. Anyway, take a look at your trailing plug hole. I never realized it is capped off. Neat. Something new everyday.

An interesting fact is that the trailing is partly covered to avoid blowing out the spark from the leading having already fired. Trailing is there to catch the last part of the unburned A/F mix, and is also why your engine will run acceptably well without Trailing ignition, but not well (if at all) without Leading ignition.
