Many years ago I got a pamphlet from Champion Spark Plug company that taught me how to read a sparkplug. It was very informative and had pictures along with verbage, I still have it somewhere. This dealt with four cycle car engines used in racing but most all of it still applies to high performance two cycle engines also. Knowing the basics of reading sparkplugs can save a engine no matter what kind of piston engine it is. I would go to Champion's website and see if they still have the info there.
