First problem was serger made a "clunking" noise...oiled it and that took care of that problem. Have cleaned, oiled, re-threaded serger several times and the thread still breaks after about 3 inches of stitching.
Serger thread breaks
1. Is the serger threaded correctly?
2. Is the needles inserted correctly?
3. Is one of the needles bent or damaged?
4. Is the tension adjusted too tightly?
5. Is the tension adjusted to accommodate thickness of thread being used?
6. Are you using inferior quality thread?
7. Is the thread feeding of the cone/spool freely?
8. Is the needle size correct for the type of fabric being used?
9. Are the needles being used the correct one for the serger?

Hi there!
This is nearly always down to the top thread tension being too tight.
At some point before the stitch-arm, there should be a tension wheel or adjuster.
Back it waaaaaay off, and spread the plates to see if there is any trapped thread in there. Clean it out if there is.
Then rethread as normal. Tighten down the top tension wheel untill you feel it bite on the thread when you pull it through. About the same drag as pulling a teacup along a table is good.
Also make sure the bottom bobbin is in the right way around. I don't know why, but it does make a difference to the tension.
If this helps at all, rate as Fixya.
If not - contact me again and we'll try something else.
Thanks for posting.

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

i have the book and it says thread from inside out, inside looper (upper) then lower, then thread the needles, first right then left. I have found that it does not matter if you thread the needles or loopers first but that you should try to thread from inside to out.

Been there, done that. Old serger almost went out the window more than once.
Raise the thread antenna and loopers to their highest positions.
Set the tensions to zero. If your serger has auto-tension, raise the presser foot as this also opens the tensions.
Begin threading from the right as indicated in your manual or on the door of the serger.
If this continues, the serger may need to be serviced as the timing could be the problem.
Ask before leaving the serger as the service cost usually starts around $100.
I finally gave in and bought a Babylock with instant jet-air threading.
