I just replaced all my plugs and no.3 on mine was also black (looked like carbon) but all the other were clean.  Don't know why though.

If the fouling is oil, could be a valve seal or piston rings
If it is soot, might be worth checking the injector for fouling, or incorrect spray pattern, of the break off preassure is out

Not every problem can be solved with duct tape, and it's exactly for those situations we have WD 40

Need to do a compression test first, then squirt some oil in the bore and retest it, if the compression goes up, it will probably be a top end prob
