Question about Singer 14SH654
I thought my blades on my serger were dull because the fabric bunches up as I sew. I changed the blades and it's still doing it. What is causing the problem?

SOURCE: serger blade is dull
You blade definitely needs replacing. It is something that you could probably do yourself if you paid very close attention to the position of the current blade before removing it and get the new blade lined up exactly the same way. That is the best place to start. Then very carefully turn the hand wheel by hand while the machine is unthreaded. You could even place a piece of fabric under the foot and see if the knife is going to cut the fabric. If all is well and there is no grinding or hitting, you should be good to go.

For normal everyday fabric, tension should be 3-5.
If it is looping on the bottom, the problem is the threading of the machine. If it loops on the top then the problem is with the bobbin.

when you have bunching on the bottom, you have a problem with the top thread: no tension. (and visa versa) Make sure the thread runs through the tension discs, these discs are activated when you put the presser foot down, so you want to thread the machine with the foot up, also feel if there no burrs, hooks, or whatever, so your top thread comes smooth off the spool, no jerking.

tension could be too loose. start with bobbin tension- should allow thread to pass with SLIGHT resistance. then adjust top tension at about 2-3 to start.

It is in your top threading. Rethread, and with the presser foot up, pull the top thread, it should feed smoothly, now put the presser foot down, the thread should barely move. This should seat the thread in the tension discs. Good luck
