I was the person from Saginaw...
I did pick it up Saturday and got it downstairs on Sunday. I've not hooked it to water yet, but it DOES appear to spin on Normal cycle, so I'm not sure what the issue was the seller was having with that.
The strange thing I've found (so far) is that the machine wants to continually agitate. When set for agitation, it is locked and transmission driven, but when it advances to drain, and spin, the agitator continues back and forth. In drain or spin, you can hold the agitator to stop it from moving, and when loaded with fabrics in contact with it, I'm sure the agitator will be still during drain and then spin with the load.
I've seen this on another BD machine I have (1982), but it is only in drain if it's running empty. And it's very slight movement, not like the full strokes of this 1971. I called this "phantom agitation" on the 1982, but in the 1971, this is more of a poltergeist!
Anyone have experience with this to know what's going on?
Thanks, and I'll post a video of this when I get a chance.
