Thanks Doug.

That's so funny about the pic qual. I bought the cheapest camera I could
find at the supermarket!!...only because I was photographing my engine
rebuild...so..it's a no name brand. Never had a camera before this, really

Hello Peter - looks good to me.  It is the insulator that we look at to see
what's going on.  The carbon soot is normal of a motor driven about, idled,
then shut down.  Now if the insulator looked like that - or heaven forbid
was bright white - a sign of too lean or the plug is too hot - then you may
have a problem.  Champion plugs used to have all sorts of charts to use
going from good to bad to ugly.  The worst one?  No insulator left - just a
gnarled mass due to detonation.
DOUG
ps - nice picture - good close up detail.  What type of camera?
