After a few minutes with some fine sandpaper, most of the rust is off, I'm sure that the wire will still snap on firmly, this seems like it would work fine as a temporary fix. What concerns me is that the rust will come back quickly...after something starts rusting, it seems like it will just keep coming back. I can't imagine how cylinder #7 was firing with all the rust on the post, I can only assume that the added resistance would hurt the spark.

When I ran my compression test, cylinder #7 had the highest at 215psi, 10psi higher than the next highest. I wonder if a lack of spark could have possibly minimized wear in that portion of the engine.
