Nothing lately. But over time, I've found bikes, a mower or two, a TV( only needed a vertical hold chip). One of my first was a Toro electric blower/vac, with all the pieces to do both functions. It would occasionally stop at just the right(wrong) place and not start up again without a small turn. Eventually, I put in a set of brushes, and it still runs flawlessly, some 25 years later.
