Can someone help me read this plug. All four of them look about the same. My guess is that I'm a little rich, but it doesn't look as bad as what's on the spark plug guides. My car sputters a lot at when it's cold, mostly between 1000 and 2000 RPM's. Seems to run fine after warming up ~ 10 minutes of driving. I use 93 octane gas and the timing is set at about 15 at idle and maxes out at about 30 at 3000 RPM.
Plug is a champion N5C.
If it is to rich, will the plugs clean up after adjusting to leaner or do they need to be replaced.
Thanks,
David
