Well, got a little overly excited with some new snow tonight. Flying through the yard turning and hit a patch of ice, tipped sled on its side. After that the thing ran like hell. Didn't want to go, sputtered etc. Brought it in, shut if off, looked everything over and its all fine. Restarted and seemed ok, but pulled up to my neighbor and the thing stalled. Tried a few times to start it, had to give it a lil gas to get it going. Is this part of some PITA safety feature, or could it have been the first rich mix tank crapping up the plugs?
