here is a picture of one of my plugs, this is the one closest to the firewall, the ones at the front looked just a nice, maybe nicer. I had been running with a super rich condition previous and did nothing to the plugs after it started running good912 sparkplug.jpg. Now the engine is running super nice. I removed the plugs to regap for winter and to clean thinking I needed to do it. I didn't clean them just regapped for smaller gap(.022) for winter. Anyway I was quit surprised on how they looked. I feel the plugs looked so good because I put a cross over of 1 inch on, from hal Stockman. I will say not only was the plugs very clean but now the engine runs like a top with NO miss what so ever from idle to full rpm.912engine (1).jpg
