I can only use three threads on my serger with the left needle. If I put the right needle in it continues to break. The upper looper is going behind the right needle instead of in front or vise versa. How do i correct this.
All help would greatly be appreciated.
Husbands gone fishing..... I've gone fabric shopping

Well darn that right needle. Sometimes all you need is a larger needle or you might need to lengthen the stitch or loosen the tension on that needle. Usually breakage of a needle occurs if the needle is not inserted properly, so make sure your set screw is tight and the needle is not slipping down. Push the needle all the way up into the needle bar as far as possible. Your needles will not be equal, one will be longer than the other when inserted. Another cause of breakage is pulling on the fabric either from the front or behind..let the serger do all the work..it will gobble it's little self silly. Pulling or helping the fabric can cause the needle to bend and break loopers.
Retrace your thread path..your needles need to be threaded last and the lower looper thread should be over the top looper arm..this does make a difference especially in certain models.
Is your serger set for a narrow or a 3 thread stitch (this was my first thought). You might need to widen the stitch or stitch finger adjustment. Be sure you are using the proper needle plate and foot if your model has several otherwise your needle will collide with the plate or foot and break.
If you are pulling your threads through by the tying on method, don't pull the knots though the needles eyes. The knots can break the needles eye. Thread them by hand. Make sure that threads are deep seated in tension disks and be sure your thread antenna is pulled all the way up.
I hope this helps. Good luck to you.

The needle bar in a serger can be rotated, and since the center point is between the two needles, if it is rotated incorrectly, one needle will be forward of the other. If this is the only thing that is out of adjustment (far from a sure thing) you would merely need to loosen the clamp that drives the needle bar just enough to rotate it this tiny bit. This is also how you move the needle bar up/down to time it, so you must be VERY careful that you don't alter this at the same time.
