Alright, well tonight's efforts included pulling the tank, pulling the plug wire, and trimming back 1/4" of the plug wire at the coil side. I can't really say if I did anything significant here, I guess the wires may have been a little enlarged where they were in contact with the threaded thing coming from the coil, so I guess the new wires may be against that threaded thing a little tighter now.
the second picture is "before trimming," and the third picture is "after trimming." Not shown is what it looked like after I spread the wires out with an awl, prior to shoving it back onto the coil.
