Black smoke is unburnt fuel. I don't have much experience with Toys but sounds like the knock sensor is shorted out making it think it has a wild knock and is dumping fuel in to it to stop it.
It's unfortunate about the service at Chair 9. It is a really good place but I think they were completely overwhelmed by how many people showed up last night. Anyways, most of the people working there were more worried about when Baker Ski Area is gonna open.
