An even easier way to clear a flooded saw is to pull the cord with the throttle wide open. You don't need to wait or remove the plug.

It's a great saw. Mine 23 years old, and my first issue, broken shut of wire. I don't flood it often, but when you do, it's rough. Of course we all don't want to wait hours to it cools.
As to throwing a chain. Is the bar noise sprocket ok. How did it happen? Slow speed, grabbing a small twig?

Throwing the chain happened while cutting but it was so fast I couldn't really tell you. I was clearing some small vines brushy crap from around the base of a small tree before I felled it though, and some of that crap was kind of grabby. Dropped the tree, and then on maybe my second bucking cut the chain came off. It came off again while bucking firewood on some logs that were just delivered. Only cutting bigger stuff that time, the chain was just way loose. This last time cutting with it I tightened the chain a bit more than I usually do and I cranked the bar nuts tighter than I usually do. That held and didn't seem to loosen at all. It's worth noting again that it's only had 2 tanks of fuel run through it at this point, so it's possible the chain is still stretching.

Do you hold the bar up when tightening the bolts? if not that could be your problem.
