    Scott, very true. Using the recommended plug should work every time unless there are any of the other issues evxident. I will make one additional comment, the newer Champion plugs with the siffix "C" for copper, don’t work nearly as well as the ones with the suffix "J". I found that the NGK plugs recommended for replacement of the J 6 J work very well.
