Review on 🔥 Craftsman Champion Spark Plug RC12YC - Pack of 2 by Thomas Taylor

My Craftsman YT3000 mower uses spark plug #RC12YC as I have confirmed on the sticker under the hood. This spark plug was installed well, but when I lit it the engine boiled over. After some research, it became clear that the problem was with the spark. I then installed the second spark plug from that kit in case the first one was bad and also spattering. I then fitted the original spark plug I was planning to replace (which still worked, just the old one) and the engine ran fine.
