Stator Autopsy on 1987 Mercury

On a 1987 Mercury 2.0-liter150-HP:
In another thread I complained about a miss fire at idle, but the engine ran very nicely at medium and high RPM without a miss. It was suggested that the first culprit to look at might be the stator, so I got a new Mercury Quicksilver stator.
Upon examination of my old stator, in addition to the red and blue wires having that soft rubbery noodle feel—the big thing—the two yellow wires had hard dried, discolored, cracked away insulation. I wonder if they got hot?
Has anyone seen this failure mode before?
