So when I was winterizing the Sunsport I found the three rear (port side) spark plugs wear black as night. The rest of the starboard and the front port cylinder plugs were fine and looked great. Anyone have a clue as to why my three others are looking as if they came out of the two-stroke engine and fouled?
FYI, the engine runs like a top. I don’t hear a hesitation or any major knocking or anything of the sort.
