I don't even want to count how many I have found over the years. Shop pack box of J19LM (24 plugs) that would run for about 5 minutes and quit. NGK plugs used in Honda ATV's that will fire between the center electrode and the plug housing not the normal spark gap which won't fire under compression about a dozen times. More NGK that short out and stop firing, or misfire while trying to start in other Honda engines. Box of 4 of RN14YC that wouldn't restart hot when used in Kawasaki enginesIt’s been several months back or maybe even years that someone was having small engine problems, a chainsaw as I recall. I posted something like “it’s probably not the problem but I’d stick a spark plug in it to make sure”. Of course this thread went on a while with solutions that didn’t fix it. I finally posted “did you ever put a spark plug in it?” You guessed it, spark plug fixed it. I’ve had one go bad exactly once in my 61 years of life but I also figure it probably needs one anyway when you start having problems.
