That wouldn't pass the test for inverted flight, anyway, would it? They aren't that bad, anyway. I've never had one quit, although, I've seen a number of them replaced. Yeah, they are that bad. The newer ones are better, but my pickup is a 2000 and it went bad pretty early in that one too. The new one seems to be doing better. I think Yamaha's (and really all of them by now) experience in small engines will result in a more reliable system, so no worries.
