SOURCE: raising bobbin thread
These machines are timed by belt and go out of time a lot. Check and see that when the needle passes through the plate and travels upward 1/8" at this point the rotating hook should be right behind and above the eye in the needle,my guess is that it is out probably 1 tooth on the timing belt and can usually be corrected by removing the bobbin case and holding the rotating hookk with on ehand and forcing the handwheel with the other hand which will cause the belt to jump a cog and should put your machine back in time I hope this helps

Had the same problem.
Open the cover where the light bulb is.
Follow the presser foot rod up into the machine.
You will find a metal keeper with a set screw facing the now open end of the machine.
That set screw has most likely come loose.
Since the presser foot is spring loaded to the down position leave the presser foot raising lever in the down position.
With your flat bladed screwdriver, gently push the metal keeper to it's lowest position. If it does not go easy, loosen the metal keeper set screw a bit. Lefty loosey.
Tighten the set screw on the metal keeper. Righty tighty.

If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.
Let me know.
