I had a run motor that would get stuck and stall the generator. You
could actually give it a push and it would turn a fraction of a
revolution and stall again. I took it apart, everything seemed ok, I
just put it back together and it's been fine since. I imagine that
something must have been just slightly misaligned originally.
