Thread bunches up on the bottom during sewing

My singer sewing machine has suddenly gone buggy. Now when I sew, the thread starts bunching up on the bottom side. I can set the top tensioner for more tension, which seems to help, but I have to set the tension so high for the problem begins to go away that it reaches the thread's breaking point. So the tensioner is not the answer. The bottom spool tension is set at a normal tension. Where else can I look for the problem?

I posted a response in your other thread. Sorry.

Basically stated to check the bottom tension, which you've done. Then also check the way the bobbin loaded. Sometimes they load funny and bind. Also check to make sure its the correct size, and if plastic that there are no burrs or knicks in it.

You may also need to clean out around the race and bobbin holder to make sure no lint is causing it to bind as well.

Be sure you have the machine threaded correctly. Follow the flow intended when threading. Be sure not to skip any areas, and be sure your thread is not twisted or wrapped around your needle.

Another possibility..

One thing that happens with my Viking #1 is that it will do that when the bobbin carriage gets too dirty. Try blowing or vacuming out the bobbin carriage area, and using a paintbrush to be sure you get any long bits out.

Also, double check the bobbin tension as this is _usually_ the reason this happens, as mentioned before. If I were you, I would tighten up the bobbin tension about a quarter turn, and see how that works...just a thought.

Hope this helps.
