I've just pulled out my month old spark plugs to see if they are showing any signs of problems in comparison with one of the many spark plug photo charts on the net.
I have a black 'cloud' / smudge on the white insulator around the centre electrode of plug number 2. Its covering about 20% of the white post. The rest of the plugs look fine, nice and white and no electrode wear.
Is this a sign of carbon fouling / rich mixture / leaky injector in this cylinder ?
