The top and bottom thread tension are the usual problem. My guess is
the bottom thread is adjusted too loose. It could also be the presser
foot misadjusted or tripping the thread. It might be the feed dogs
(under the foot) slipping or falling apart. Hard to tell without
seeing it in action.
See:

Note the last photo on the bottom. If the bobbin thread doesn't pass
between the feed dogs and then towards the back of the machine, the
thread will probably bunch up.
Search Google for "sewing machine thread bunches":

I can tell you that yes, that screw controls the bottom thread
tension, and should be adjusted 'properly'. For you 'properly' is
probably trial and error.
As to your 'bunching' (tangling) of the thread, I have no idea, I've
seen this and it is a PITA...
Check your thread tension. Sounds like it's too high for the fabric
you're sewing.

It is usually the top thread which bunches underneath, check the top
threading path and whether the top tension discs are working properly
(they can be assembled back-to-front on some Singer models).
When it starts to do it again, gently pull the top thread where it goes
down to the needle and see if it there is some resistance coming from
the tension discs.

Sometimes it's just bad thread. My mom sewed most of her life, and
she always had a small box of bad thread that was used to hand sew on
buttons and such. It was strong enough, but not smooth enough to work in
the various sewing machines she owned.

That was very good advice guys. I really appreciate it. I'm going to
work on it again and we'll see what happens. Lenny.
