I'd say Bruno is the one to go to if you want to investigate the plug. He can just pull it back out and look.

I've been meaning to photograph the spark plugs I pulled, numbered and replaced with [REDACTED] but haven't yet gotten around to it. I totally want to get to the bottom of this! Thanks!

I feel like this thread needs closure. So here it is:

"OP decided that his car didn't need spark plugs and then replaced his gasoline motor with an electric motor. Strange but true."

What did end up being the issue? Obv running rich but what repair fixed it?
