That's what mine has too.
I just looked up a pix of your machine on line, and the specs say there is a dial on the machine to control tension. This dial will control the top tension. To make the top tension tighter, turn the dial to a higher setting about 1/2 a setting at a time and stitch about 2 or 3 inches, look at the stitches to see if the same thing is happening; If it seems improved try the next half number and check again, that way you will not overcompensate. I still think it could be the problem I had with mine, in which case you might try un threading the machine and taking some dental floss through the slots and then moving back and forth to see if it will clear anything that might be stuck in the tension disc. Other issues could be a needle inserted backwards or different weight threads between to an bottom, sometimes it is a process of elimination, but I always start with the tension discs first. :-)
