Anyone know where I can find a Featherweight manual? After using my old one for about 6 yrs and never a problem, I took it to a guild sew-in last Sat. and the only thing different I did was to change the top thread spool. It absolutely would not sew right, keeps bunching up on the bottom thread. I checked the bobbin, changed the needle checked the threading path. No good. Came home and got out a newer FW, checked everything against the newer one, all the same. Newer one sewed like a champ. What on earth happened? I had just used her three days before the sew-in. I sew crazy foundation blocks on her when the mood strikes. I am totally at a loss to figure this one out.
