Thread: reading spark plugs?

Hey I changed the plugs on my gtp the other day copper autolite 104, all the plugs had the nice toast colored burn except

for one, my number six cylinder was a bit lighter than the other plugs, enough to concern me atleast. Are these signs of lean

cylinder maybe a chipped piston. I have a bore scope im gona check it out and see if its chipped but wanted to get some

input first.

pics?

I threw the plugs away I did take some pics with the bore scope but they suck I can post them later
