Try these suggestions
1. Change the needle--use a needle that's for the fabric being sewed
2. Rethread the machine--top --make sure to use every thread guide
3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case
& make sure the bobbin is turned the correct way in the bobbin case
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads
6. Check to make sure the bobbin is not warped or damaged
7. Make sure the bobbin case is correctly in the machine,, if it's a top loading bobbin you may need to have the bobbin case checked to see if it's damaged or see if the hook and hook race has a problem
8. Also could be a timing problem, and the machine would need to be checked

I am having adjustment problems on my machine, it did not have an owners manual. missing stitches and bunching up underneath the meterial

Have you changed the needle ? Is the fabric a knit ? If the needle has been used for awhile, it may be dull. Many modern fibres are quite hard on needles, which need to be replaced fairly often.

Many knit fabrics require a ball point or Q needle.. [ Kenmore\'s brand of ball point knit needle]. Many knits are notorious for causing skipped stitches and a special needle for knits can really help with this.

If thread is bunching up, is this underneath or on top of the fabric ?

If it is underneath, the top tension may need to be adjusted. Mal adjusted top tension can cause a lot of problems, and the mechanism that controls it can become worn and may need service or replacement.

I can sew a few stitches did it all balls up at

Thread balling up in the bobbin case usually indicates that the TOP thread is mis-threaded (usually at the take up lever). Check with your manual for proper threading path.

HD 3000 loops underneath work

It's most likely not the machine. It's the other things, ie needle, thread, etc. combination. For sewing knit, be sure to use a ball point needle. The needle eye size is important to so the thread is neither too small nor too large for the thread weight.

FWIW, it sounds like bird nesting. --the thread is not seated completely in the tension disk. Remove the top thread from the machine and ALWAYS RAISE the presser foot when rethreading!

Also, check that the tension is appropriate for the project. The two threads should meet in the middle of the fabric. If there is top thread showing on the underside of the fabric, the top tension is too loose. Tighten it until it until the top thread pulls the bobbin thread up into the fabric.

When sewing the top thread breaks and underneath the thread is all balled up. I have a Kenmore Mosel 385.17724.

it sounds like the top thread is not being pulled back up properly
make sure the machine is threaded properly with a new needle. (sorry for stating the obvious)
otherwise you can try
higher thread tension on top thread
larger size needle.
thinner gauge thread
different material

one or more of these should cure the problem

I have an omega 3730m sewing machine and i find that when i am sewing, the stitching underneath balls up nad is not tight. i tried to adjust the tension but nothing seems to work. any suggestions?

I find that re-threading both top and bottom threads fixes the problem. Sometimes the thread has not gone through the tension springs properly. try a new needle too.

The top stitch is fine but underneath the thread is all balled up what might be the problem

When the thread is bunched up underneath, the problem is often in the top tension. The top thread is pulled through to the bottom but because there is no tension, it isn't pulled back up correctly, creating large loops underneath.

Try making sure that the thread is lying correctly between the tension disks (you can just see them inside the machine on the downward thread path). Lifting the presser foot lever (behind the machine) opens up the disks and lets the thread slide between them more easily. They will close again when you put the presser foot down to sew. Make sure you always thread the machine with the presser foot lever up and tension disks open to avoid this problem in future.

If the thread is running correctly between the tension disks, just check that you that there's no fluff caught in there, holding them open. Give it a blow, or run a folded pice of fabric through there.

Bobbin thread is balling up underneath and not allowing more than a couple of stitches before jamming.

Totally rethread your machine and install a new needle. Your thread could be tangled. Usually the top threading is the culprit, not the bobbin. Check your manual, it is surprising, sometimes you think that you have it threaded right and it isn't.
