Philly-R6 28 Posted October 14, 2020 Report Share Posted October 14, 2020 According to Haynes: If they are clean and white, with no deposits, this is indicative of a weak mixture or too hot a plug (a hot plug transfers heat away from the electrode slowly, a cold plug transfers heat away quickly). If the tip and insulator are covered with hard black deposits, then this is indicative that the mixture is too rich. If the plug is black and oily, then it is likely that the engine is fairly worn, as well as the mixture being too rich. But if the insulator nose is covered with light tan to greyish brown deposits, then the mixture is correct and it is likely that the engine is in good condition.
