The reason for the post was whether to pull out the spare 401, which hasn't been touched since I bought it. I don't remember if it was frozen up or what condition it's in. I would give it to someone if I was sure I could fix the current 401. The 301 pieces so perfectly and fast that I'm unlikely to to go back to piecing on the 401. However, The two 401's are the only zig-zag machines (besides a T&S) I have, so I want to keep one.
Unfortunately, I was hoping I could get an answer without having to work on one of the machines (or both). I guess I must be dreaming.
