Yeah, I don't know how you the clutch drum could spin with the brake on to make the groove. I have a strong ms311 in my garage and it won't move the drum with the brake on and if the drum is spinning it stops instantly at WOT...and the brake is pretty hair trigger so I don't see how it could be a partially engaged brake unless the spring was weak or something.

Could oil or water on the outer surface of the drum allow it to spin with brake on?

I appreciate when posters like you try to think outside the box and come up with different scenarios. The guy from Stihl absolutely would not back down from his stance about the chain brake being on. But as I said before, he has seen a lot more of them than I have, and some of the more experienced on here seem convinced of the chain brake/operator error scenario as well.
