:confused2:I just wanted t o make a post to see if anyone has ever had or heard of this happening.
I have a johnsered chainsaw, and its about 5 years old. Never had the plug out of it until today.
I was cutting thought three tanks of fuel when I heard a tinny noise much like a loose piece of tin. I shut the saw right down, and it wouldnt start again. I then removed the cover and when I touched the plug it was already loose with some black smoke marks around it. I thought OK loose plug NP.
I then removed it to find that the small metal that is bent over to the inner electrode was gone:licking:
The engine would crank over fine and I made sure that that metal part wasn't int he cylinder I put in a new plug and it runs so far..
its it possible that it broke off? burned up? and got passed through the exhaust valve?
Or possibly slow wore down to nothing?
Either was I assume it was just vibrations and expansion that made it loose to begin with.Maybe I should a checked it for tight before.
