Where can the inside loopers or needles be purchase?

Hello Mary.
By the question, it looks like the lower looper is making loops? If so, check that you are using the correct needles for your serger and that the needle or needles is/are inserted correctly:
- needles must be all the way up into the needle shaft
- needles must face with the flat side to the back and the groove to the front
- use at least needle size 12/80, not smaller

Check these few items, if the loops are still not forming:
- re-thread the serger from the start, keeping in mind to thread in the proper sequence (upper looper, lower looper, needles)
- make sure that the lower looper thread lays on top of the upper looper thread and is passed to the back of the serger and then under the presser foot when threading
- make sure that the thread are securely engaged IN the tension assembly
- make sure that the serger is set for 3-thread or 4-thread overlock (i.e. that the upper looper converter is not engaged)
- check all tension setting
- stitch length should be around 2.5 - 3.5

Let me know how it goes.
Happy serging!

Start with the threading sequence. Upper looper, lower looper, left needle, right needle. Your upper & lower loopers must be threaded before your needles or it won't make the stitch. If it still doesn't work, it's out of time and will need to be taken in to a shop.

Here are a few things to try.
1. Make sure that correct type of needles are being used, both are the same size, and that the needle size matches the fabric weight. This is the first serger to use 15X1 needles.
2. Make sure that the needles are installed correctly and are pushed all the way up. Have you replaced the old needles with new ones, not other used ones?
3. Thread has a shelf life, it can expire over-night. Just to eliminate this possibility, replace all threads with fresh good quality serging thread (and not just another spool which was purchased some time ago).
4 It sounds like you have re-threaded the serger correctly according to manual instructions. Here is a sure fire method:
- thread the upper looper and place the thread behind the needles under the presser foot. Make sure that the thread is lying firmly between the tension discs.
- thread the lower looper (the tricky one). Check that the thread is between the tension discs as before and place the thread over the upper looper and then behind the needles, and under the presser foot.
- thread the needles, checking that the thread is between the corresponding tension discs. Place the thread under the presser foot.
5. Check stitch length.
6. Check if the problem persists with other fabric types, use two layers. If the problem occurs with only a particular fabric, then the cause is incorrect needles.
7. Check tips on both upper and lower loopers. They should be free of burs, smooth, and have a semi-sharp point.
Hopefully this will solve your problem, if not it may be time to have it inspected by a qualified technician.
Please rate how effective were these suggestion in solving your problem, it is important to me.

First take all the thread out of the machine. Put in new needles and run the machine slowly by hand and see if there is a problem with timing. If the needle hits and bends or breaks... take it in to be timed. If the needle don't hit....

Make sure you are properly threading this thing. Unlike a sewing machine which gives you some leeway, Sergers must be threaded in a certain order. Typically, upper looper, lower looper, right needle left needle. If you break a thread you can't just rethread that thread... you have to start from the beginning.

You might check singerco.com for the manual for this thing. They have most of white's manuals online they are identified by a W before the serger model number.

Open up the front cover. There should be a diagram right there, and you want to thread your serger step-by-step per the color-coded diagram so that the needle is in time with the movement of the loopers. If you randomly go about threading it instead of in sequence, the threads will collide and you will create a jam. The usual threading order: Upper Looper, Lower Looper, Left Needle, then Right Needle. Do you have long serger tweezers? Do you have a Looper Threader? If not, these are great tools to assist you as the Lower Looper is threaded right to left- an eye all the way to the far left, so it helps to have the tweezers and Looper Threader to maneuver in this very tight area. Many new serger users don't realize that other eye is "hiding" and miss threading it! Hopefully, you have a manual with additional pictures to help guide you. If you need a manual, try allsewingparts.com and perhaps they have one specific to your serger. Note: When you insert your needles (make sure they are #11 and #14 specific for your particular machine), the left needle will be the same size as right needle, but will APPEAR higher once both are pushed up into each of their respective needle shafts. Note: Hold onto needles or put a piece of fabric under the area when changing them/replacing them because they can easily fall out causing damage to your machine. Hope this helps. Jimmy

From what I have read this manual is less than desirable. Neither is the one for the brand that I have.

You may have better guidance if you purchase and use Nancy Zieman's "Serge with Confidence". I have found it very helpful.

For the two thread rolled hem, the looper cover is used to "trick" the looper into "thinking" it is threaded.

On my serger (not a Bernina), this is referred to as a "subsidiary looper". It is a spring type mechanism that fits in a small hole at the top of the upper looper.

You use a rolled edge presser foot; right or left needle; stitch length @ normal or wider; stitch length @ 1mm for the left needle/0.5 for the right needle; differential feed @ normal; needle tension - tighten; lower looper tension - normal or looser; two thread looper cover - engaged.

Test and adjust the tension as needed before making the rolled hem on your garment.

I hope this helps.

i was able to find manual at www.ifixmachines.com

The order of threading is most important. If you letter the tension knobs from left to right A,B,C,and D. The order for threading it is C,D, B, A. There are two arms under the needle that cross each other called loopers. The order is upper looper, lower looper, right needle, left needle .I'm sure there is a diagram under the cover when you open it. Most do. It would be very helpfull to use a long threading tweezers to guide the thread through the holes. The lower looper has a hole in the back to put the thread through then through the front hole ( though some newer sergers have a lever that you put the thread on and it does it for you and over the thread of the upper looper and out the back.
It would help alot more if I knew the brand and model of your serger so these are basic instructions. Hope I helped.

I ended up switching the spools of thread around. Apparently, even though I had purchased good quality threads, one of the spools was wound in a way that made the thread loop and twist around. So I put the offending spool of thread through one of the needles and put the needle thread on the upper looper. That seems to be working. By the way, BabyLoc was very unhelpful dealing with this problem.  Thank you!

Solution taken from "Handbook for Huskylock Sewing Machine Models 1001L/1000L/1000"

1. Raise the presser foot by using presser foot lever. When the presser foot is raised, the two thread tension discs in the thread tension control panel are released so that thread passes freely between them. Otherwise thread tension may not be correct.

Important! When threading the needle, always be sure to lift the presser foot lever, and also take care to thread in the proper order.

Threading order:
1. Upper looper thread (green)
2. Lower looper thread (blue)
3. Double chain stitch looper thread (purple) in case of 5 thread stitch or double chain stitch
4. Right needle thread (red)
5. Left needle thread or double chain needle thread (yellow)

Caution!
Because the left thread tension dial (yellow) is used for either the left needle or the double chain stitch needle, these needles will never be used at the same time.

Upper looper (green) sequence:
1. Thread holder (silver triangle openings attached to thread holder stand)
2. Thread guide (flat silver clips just behind thread tension disc)
3. Thread tension disc (circular knobs with numbers for tension setting)
4. Pull thread around upper looper guide and upper looper
5. Pull thread into hole of upper looper

Lower looper (blue)
Repeat 1, 2, 3.
4. Pull thread around guide (see color coded chart inside front serger cover).

Easy threading mechanism (for lower looper)
1. Pull out the lower looper threading lever
2. Thread the lower looper and position the thread on hook of the lower looper
threading lever.
3. Push the lower looper threading lever back to its basic position while
holding the end of the thread.

Caution:
When returning the lower looper threading lever, always make sure that the two
blue triangle marks (directional arrows) meet each other.

Right needle thread (red)
Left needle thread (yellow)
Important: Thread the needles after threading of lower looper and upper looper.
First raise the presser foot lever, and then thread the needle threads in order shown in color coded thread guide.
