The seam does not pucker.
I would have tried switching parts with the 401, but at this moment, it doesn't seem necessary. I've sewed three long, very fast seams with no problems so far, but have not yet tried it on a quilt. The difference is that I followed Joe's instructions and measured and adjusted the part that holds the bobbin in, and I used a Schmetz 90 needle. Oh, I also flossed the tension thoroughly. I did catch some shredding there. I haven't done anything about that (crocus cloth) yet because of the three good seams. My philosophy is that "if it ain't broke, don't fix it."
Thanks, Joe. I did check and adjust all 4 specs together. Sorry if I wasn't clear.
Good idea on setting gaps in the middle. I'll remember that and do it next time.
Maybe I am pulling the fabric. It is hard to handle a quilt in the space of just the cabinet. I don't have any other tables upstairs to support quilts nor room for them. I do have them downstairs but I also have knee issues and stairs are not doable right now. I'm guessing it isn't out of timing because the stitch remains perfect. Would you agree? Also, I see no needle marks or indications of timing problems. Unless you know something I don't? If so, do tell, please.
I will try to quilt my quilt and I'll let you know how it goes.

Hey Cricket! How's Jury Duty going? Have you had a chance to sew with the machine?
The reason I asked about the seam puckering when the thread breaks is I thought that maybe if one or the other puckered, it might let us know if it was being hung up. Oh well.
So you haven't disassembled this machine's tensioner? Only flossed it? You may find you like the end result better if you disassemble and clean. I do every one of them now as the first order of business.
I don't suspect timing, no. There's a series of articles on my blog about timing. It covers most things - not raising the needlebar but otherwise pretty much all you'd ever need to know.

I'm with you Joe, that bobbin would have hit the bin so fast...
