Well, I did the Governor clean up and found the parts in pretty decent shape. No apple core, or muck to clean off. I did polish any scuffing on the parts with some emery cloth and rounded off the edges to ensure movement without sticking.
I'm amazed that it solved the problem, at least in the short term, so far.
However, I think I will be doing the EJ swap that GD is talking about in the near future.
I'm really surprised. I didn't think that the governor needed needed a significant enough amount of polishing to make a difference since it was in such good condition.
Thanks to all for the pointers and the information, eh. Problem solved. Hopefully it will last until the EJ swap.
