Hey Billy,
What do you think of the sound a 301 makes when it is running? I have never heard a gear driven Singer before. Should I be hearing the gears? I took off the top plate and bottom service plate, checked to see the gears look like they are meshed properly, not too loose or tight, cleaned off most of the old grease, put on new, not so much as would sling around at high speed. It sounds smoother, but still a bit like a wind up toy on steroids.
This one is 1951 date. I could tell by the top plate screws that it has been serviced sometime in the past 60 years, but the gears and inside look suspiciously clean of built up gunk.
Don't know a thing, just asking.
Aardie.
