unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..

1) It’s possible the machine is threaded incorrectly. Remove the thread completely and rethread the machine. Be sure to use good quality thread--don't buy the cheapest you can find. A good thread will help your machine perform better and your projects last longer.

2) Poor stitch quality can be caused by the needle. Make sure you're using a new needle that's right for the job. Many times machines are taken in for repairs and all they need is a new needle. If you can't remember the last time you changed the needle--it's past time. Needles should be changed at least every eight hours of sewing.

3) When inserting a new needle, make sure the flat side of the needle faces away from the bobbin area. For example, if your machine has a frontloading bobbin, the flat side of the needle faces the back of the machine. If your machine has a side-loading bobbin, the flat side faces the right side of the machine. Some older sergers require special needles that don't have a flat side. Refer to your owner's manual to properly install a serger needle.

4) Thread that shreds or breaks can be blamed on the needle. Use a good thread and make sure the needle eye is large enough for the thread type. Also use the right type of needle for the fabric;
5) The machine tension adjustments put stress on the thread so it doesn't simply flow through the machine. When the upper and lower tensions are balanced, the stitch forms correctly. Tension is easy to adjust--stitch on fabric samples with a different thread colour for the upper and lower threads. Observe the stitch, adjusting the tension until the stitch is formed correctly. As a general rule, adjust the upper tension first. If the stitch still isn't right, adjust the bobbin tension.

Take the bobbin case out. Then when you go to put it in, realize there are 2 ways to get it. You have found one way. The other way is first look in the the slot with a flashlight before you insert it. There is a flat piece of metal the bracket needs to be slid under as it is inserted. This acts like a spring making it tight

From what I gather on other sites, your thread has to be threaded under tension.... You have to make sure you hear a click when your bringing your thread down to the bottom of the "arm". Also, I thought the bobbin case was rather loosely held in its place, I adjusted this by unscrewing the black plate and moving it over just a smidge. The bobbin is supposed to have some wiggle room, but it kept popping up and making the tiny adjustment seems to have done the trick....for now...

Make sure the bobbin case sets sort of on top and not under the ridge of the metal ring. There is a small latch on the upper left of the bobbin case. It is metal. rotate the latch to cover the bobbin case and this should stabilize the case without making it immobile
