As with chain saws & lawn mowers....when they fail to start after a starting struggle, let them sit over night and they always seem to start the next day.....I'm reading a lot of anxiety in your post, at least its at your daughters house, and not in Lowes parking lot..... A good night rest & a fresh start on a new day might solve the problem. I don't think a short over rev did anything.........Good Luck.....Oh by the way 'limp node' I guess we can rule that out.....What rocket scientist invented that?....just can't get past old school technology....
