301 tension
I'm trying to FMQ with a finer thread, Superior 40 wt, and neither of my 301s can hold the tension. I can't switch to another of my machines as all the ones I have in the house are short shank and all my FM feet are slant shank. I did bring my 404 home from church today to see how it does. I've never FMQ with a horizontal bobbin, but at this point, I'm willing to try. Any thoughts on the tension on the 301s? I don't think I can find a repairman locally. Both have been iffy on tension for a while, even while piecing. The 1956 has had the spring replaced by my son, but not recently.
