My 401A hasn't been the same since . . .
I loaned it to a friend because she wanted to make a summer quilt.
She said the needle broke on her and she replaced it but decided to buy her own machine. So they gave it back along with a new pack of needles.
I started to sew . . . broke the needle.
Cleaned and defuzzed the machine. Put a needle back in. Broke again.
Looked around to see if anything was hitting but couldn't see it.
Oh, it breaks when I zig zag.
Hoping someone out there has had this problem before and knows how to fix it.
