Naw,.. this one is a relatively recent conversion. It's a BAJ3-8 motor, same as the ones that come stock on the 99K machines.
It's the sound of the shuttle moving faster than when I treadle. The weird double bounce that the needle does seems to be a good part of the noise. Of course, this is also without a full cleaning / oiling/ tuneup, but on the long bobbins, it seems like there's always noisy play with the shuttle in its holder. That's the noise I hear, just louder and faster.
It's not going to shake the house down, just enough to make me go "Wow! That's noisier!"

That's exactly the noise I'm talking about. Imagine that about 1.5 to 2 times faster than you usually treadle. (Or at least it is for me with a motor)
