Spark plug that is...
Also found out my screw extractor set is missing the biggest one, and the #4 is just not quite big enough to do the job.
Bad news is that the #4 extractor is small enough to screw itself inside the plug, then not be able to get back out, so now that's stuck in there too. Need to figure out how to pull while turning in limited space. Not quite enough room for visegrips.... Big ass needle nose pliers can't grip it enough... :(
Quit for the night. Drink beer. Look at it tomorrow. :(
