I honestly wouldn't know if he had it upside down on the throttle or not. It's not a scrape or gouge but a mark from one of the detonations. However, it may be from having a rich setting (which he said he ran it rich) and the plug element dropped in there. Either way, it wasn't anything more than a surface difference. Should I be worried?
