genny would be smoke. That is if you were lucky. It would be out of

It wouldn't stay that way for long. The mains would motor such a small
generator into sync in very short order. Wether the alternator would
survive is debateable and the engine might not like it that much
either but if it stalled it would be started again...

Not something you see happen very often these day on the grid, a
generator being bought online out of phase/sync. I've only seen the
effects as a consumer once probably in the early 80's. Voltage going
up and down from full to not al lot at about 1Hz with amplitude of the
voltage excursions decaying over about 5 to 10 seconds.
