The chain was purchased in 2008 and checked two months ago and found to be good (not verified by me). I did check to see if the tooth was engaging the chain early, or on the upper part of the tooth, but it doesn't. It touches near the root for the links that do not have the problem. The tooth does not even touch the side plates, internal or external before engagement, so it is not "riding" on top of the teeth at all. If that were the case, the chain line would be the first suspect variable.

The jumping is after the point of the tooth is past the top of the chain. I will take a video and post it.
