P.s. My FMQ spring broke it made such a racket decided not to get it replaced, use the plastic embroidery foot and get along fine.
Do you have one of the older ones? When I researched prior to buying mine, I had read that there were tension issues but that they had been resolved. The only time I have that issue is when I don't have the presser foot all the way up while moving the fabric. Also, on the older ones, I have heard that the thread can come out of the last upper thread guide...another thing I think they fixed. I had heard that if you thread that guide left to right, rather than right to left, it helps.
