Question about Kenmore Drop-In Bobbin 16231 Mechanical Sewing Machine
If the looping is happening on the underside, it is your top tension that is to blame, conversely looping on top is bobbin tension.........take a look HERE for detail on cleaning lint buildup.
Top tension should be set around the middle of the range, usually 4 - 6.
I would not advise playing with bobbin tensions, however, you can take the needle plate off to clean the hook race area (where bobbin case sits) ...this is good housekeeping, my wife does this every time she replaces the bobbin....just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint, if there appears to be fine dirty deposits, a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit will do the trick.

Thanks for the above solution(Jan 27th). My bobbin tension was a mess and I simply took your advice and adjusted the top tension and now it's perfect.
