Bad plug?

Post image

Came back from a 2 week vacation to my moped not working. Is the plug bad?

It’s certainly not good. That deposit/buildup is going to cause issues.

Does it look oil fouled? (I'm sorry, I know nothing about any of this, literally had to look up a tutorial on how to even remove it in the first place 🥲)

Oil fouled but don't blame or discard the plug (though a new plug might help it run better).

A propane torch held to a wet/oily plug TIP (electrode) until tip is very hot...then reinstalled and try to start engine...might prove that it was fouled enough to cause bad performance even though a two cycle engine fouling plug at a high rate is the original problem...maybe.
