No problem, Ant. I'll take some clearer pictures and repost. The ones I posted are a little fuzzy due to using my phone instead of my digital camera. But one should get a good enough idea from them anyhow. I have a few other plugs somewhere with really crumpled and mushed elements from a lean run. Over-compressed engines will just compress the element usually leaving the element round, just pushed way into the plug cavity. I'll see if I can find those plugs and get some photos of them as well.
