parts can be had... Call your local dealer and tell him what you need. It should be pretty standard but they would know what to give you. Or call brother direct.

Try a different needle. Use a quilting or topstitch or even a metallic needle - one that has a larger scarf than normal. The scarf is the groove at the back of the needle where the thread goes while the stitch is being formed. Quilting threads often need more "room" there. I have been told that the Inspira quilting needles are good because they have a thread groove on the front and the back of the needle. Not tried them personally but might be worthwhile for you to consider.

For the looping, you could fiddle with your tensions a little either loosening the bobbin tension or tightening the top, or both. Only ever do this in very small increments. But the good news is that even the "professional" quilters do not have perfect quilt backs - just have a look at them at quilt shows!

If the machine is not picking up the thread it may need retiming.

try changing the needletry tightening the top tension one number or letter at a time till the stitch look bettertake the bobbin out & reinsert the bobbin into the bobbin case, also make sure the bobbin is not damagedclean under the needle plate & in the bobbin area for loose threads or lint

try these sites--you may have to email them about the partsewingpartsonline.comsew4less.comsewvacdoctor.coma1sewingmachines.com

try adjusting the top tension to a lesser number---the lesser number is looserthe higher number is tighter

Make certain you are passing the thread through the tension for the bobbin winder when setting up to wind the bobbin. Check that tension assembly for anything that could be stuck in it, preventing the assembly from putting tension on your thread, such as another thread. Wiggle the disc on the assembly to make sure it isn't stuck. If none of that works, disassemble that assembly from the top of the machine (NOT the tension you use when threading to sew!) and see if the spring inside is broken. If it is, replace the spring if you can get it, or the whole assembly if you cannot.

is the bobbin inserted in the bobbin case correctly?is this a drop in bobbin?is the bobbin bent or warped?
