SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

Maybe the drive wheel is disengaged. Some machines have you pull out the wheel on the right to wind a bobbin and yours might be pulled out. Try pushing the wheel back in to engage the machine.

The problem is likely the threading. Double check the threading, look twice or three times at the diagram. Even me, a tech sometimes threads a machine or serger wrong.

Always remember that it is the opposite of what you think, it is your upper thread that is not threaded right, not your bobbin. Once you thread it right, you should be okay. You can buy a manual at sew4less.com for about $14.95

Are following these instructions? http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Singer_Sewing_Machine_Threading/singer_401_threading_diagram.htm

Note: always thread a sewing machine with the presser foot up and make sure the bobbin thread is feeding from the bobbin as indicated in the manual.

Tension is usually around 4.

You need the right bobbin for this model: Class 66.

Machine won't sew


Change the needle and be sure the flat side is to the back. Rethread the machine. Remove and reinsert the bobbin. Hold the top thread and turn the handwheel to see it the top thread will pick up the bobbin. If yes, it should sew ; if not, it is probably out of time and needs to be seen by a technician.
