I have taken off the lower case many times. Removed lint/dust and a broken needle. Top thread Keeps catching on the bobbin instead of sliding over. Any tips greatly appreciated
SOURCE: Top thread won't catch the bobbin thread
First check the upper and lower tension adjustments according to link below and then check the knob (bobbin case) that makes the bobbin tension which lies inside the shuttle if it is too loose. Restricted it with the sheet metals around it so that it shouldn't move so freely up and down or back and forward. Be careful it should move freely a little but not too much.

SOURCE: Top thread will not pick up the bobbin thread.
(1) Check the needle or replace with a new one. A needle has a groove in one side of it and that is the side that the thread enters the needle. Some thread from the side and some from the front.
(2) Before sewing, manually turn the wheel to make the needle go down while holding the needle thread with your left hand. When the bottom thread pulls up, pull both threads toward the back of the machine before sewing.
(3) Make sure your pressure foot has been lowered. Sounds silly, but if you lift is high it might just look like it is engaged.
(4) Try it on two ply fabric first and try both a straight stitch and a zig zag and see if you have problems with both.
(5) Make sure your thread is really machine thread and not hand sewing thread.
(6) Make sure the bobbin thread is feeding off the bobbin spool in the right direction.
(7) Anything other than these is probably a tension problem or a timing problem.

it's sounds like the machine could be out of time & the machine needs to be checked at a sewing machine shop, to find out for sure.
