You're not hearing what I am telling you.....I told you NOT to use the pluig as a test. Here is the reason: If you look at the spark across just the normal tiny plug gap in open air, and it looks weak there, then you WON'T have a working spark in the engine. A 3000-4000 volt spark (which is weak) will jump that plug gap outside of the engine, but it will take 20,000-25,000 volts to jump that same gap when IN the engine. DON'T use the plug out of the engine as a test method.
