Hi Stan,

For the sake of discussion- can you please define the look of a
"lean-burn" sparkie?

And really, no joke- does someone have this simple stuff posted?
Or- if I find a photo, does someone have a spot where I can post a
pic of sparkplug appearances/conditions/symptoms after being run
in an engine?

Cheers,
MIker
