Good, if it didn't get too hot and good you had some oil, I really don't want doom for you. As for the impact, if others are talking about hammering on the thing as you use a breaker bar, what's the diff? Either probably has equal chance of working and unless you go ballistic you probably won't crack the housing. I like the idea that maybe the rotor and stator have come to grips, there's gotta be some reason why it stuck. But then, if it was running, sounded like gas starvation, jeez if the stator was grabbing the rotor, you ought to hear it. Oh well easy to check. Good luck!
