Bobbin thread is jammin up after about 3 rotations of wheel on my janome 8077 - is this a timing problem?

SOURCE: bobbin?

DO NOT RESET THE TIMING!! The timing is off on maybe 1 in 100 modern Husqvarna machines. For the user to change the timing is turning a simple fix into a complicated and expensive fix.
If the top thread is "looping up on the bottom" then you have a problem with the tension on the top thread. Here is what to check:
1. Thread the machine all the way through the eye of the needle. Don't go under the foot.
2. Pull the tread to the side. While pulling, lower the presser foot. You should see the needle bend as the thread gets tight. If not, you have no tension on the top thread.
3. With the bobbin in the case, hold the needle thread and turn the handwheel to bring the thread up. Watch through the cover to see if the thread passes over the bobbin from left to right. When it gets to the right side, the take up lever should pull the slack out and the thread should be pulled up. If it comes part way across but does not pull up, make sure the thread is in the take up lever. If you never see the thread, remove the bobbin case and turn the hand wheel. You should be able to see the hook pass behind the needle while the eye is still below the level of the hook. If the eye is above the hook as it passes the needle from right to left, then and only then consider timing the machine. If the hook passes above the eye but doesn't catch the thread (bobbin case out, needle plate on, presser foot down) you probably have a problem with your needle. Put in a new needle and make sure that the flat side is to the back.
99% of the time when a Husqvarna is not picking up the bobbin thread, something simple has been overlooked. Your symptom of looping on the back of the fabric indicate either a threading or tension issue in most cases, not timing.

Sounds like you have to take off the throat plate and clean out threads under it.  Sometime they ball up and prevent the needle from going down and catching the bobbin thread. You can't see themuntil you take off the plate.  Follow the directions.  It is easy.

SOURCE: Thread in needle or bobbin keeps on breaking

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

SOURCE: Top thread won't pick up the bobbin thread

re insert the needle, maybe you did not put the needle up as far as it is to go. Make sure the flat side of the needle is to the back of the machine. Without any thread in the machine hand turn the wheel and look to see if the hook of your bobbin would/could catch the thread (to see if timing is right)
then thread the machine and hand turn the wheel and see what it is doing.
Your timing might be off, but I do not think that is likely. Though it is possible that when the needle fell out, it hit something hard, broke, and pushed the machine out of timing. then you need to bring it in.

timing issue, need to have serviced.
