Anyone think the wrong gap on this spark plug coulda caused this or do I just need the next colder range? Or maybe just a good cleaning & smoothing it up some with JB Weld? With the price gouging going on at O’Reallys because of C19, just needing a way to bring some new life into this without breaking the bank. Awaiting an answer.

@CoggedBelt75,

C'mon now, how'd this happen? Did you put a little bit to much advance before you stuck your foot in that monster blower?? My brain is working overtime trying to figure out what would melt a plug, I've heard of this but usually what happens is the whole end of the plug is melt...Wait, I remember!! It's the pro dragsters running all that nitro. They say that it's so hot that it literally melts the plugs out of the head. That when you see sparks coming out of the exhaust pipe it's the plugs melting off!!

Just slap some JB on it and make sure you run double the giggle gas next time so that it protects the plugs(by melting the piston first).

Got rid of the gas in ‘07. Only knocked the top 2 lands off of 3 pistons but didn’t hurt the plugs. Pretty sure I’ve changed plugs since then tho. Only running 10lbs of forced air now. Maybe sealing the side gap up I could get 11. And @John Nes , I may have used too much never seize on it. Figured that was what was running down it.
