Do these look like my tune is good? First time pulling the plugs and thought I would ask.

tad bit lean,but look OK

Looks a tad rusty to me.  What's up with that?  Otherwise, looks normal for the lead free fuel and emission control era.  Light tan to white insulator, no signs of heavy carbon deposits that could signify a rich condition or excessive oil consumption, no signs of abnormal combustion or abnormal erosion of the electrodes.  Of course that's only the part we can see, the other area to look at when trying to read plugs is down at the base of the insulator where it meets the shell, using a lighted magnifier.  Not many actually read plugs to check mixture these days, since we have electronics that do it more accurately.  Kind of a lost art.

Not sure about that rust either, it came out of the rear.  All I can figure some water puddled there one day...

Thank you for the look and reading.
