Check to make sure that the top thread is staying all the way inside the tension disks

This happened to me a couple days ago on my Jianglong 341. The TEX 270 thread would be inside the tension disks at the beginning of the seam, but by the end of the seam the tension disks would be flat together with the thread only skirting their perimeter. That's when I decided to add some tension to the smaller/auxiliary tension disks right next to them, which I had never found a use for previously. But it seemed to keep the thread properly seated in the main tension disks.

I would do the drop test for tension on the bobbin thread

How does one do the drop test with a vertical hook shaft?
I tried it but the bobbin fell out of the bobbin case cap.

I think some of your problem is you are using Tex 270 (V277) which the machine is not rated for. The 341 / 1341 clones of the Juki LS 341 or 1341 are rated for a #24 needle which will accept Tex 210 (V207) but the machines typically will only sew that in thinner material. A lot of clone machines rate their machines on the max size thread you can stuff through the eye of the needle vs Juki rates their machine on what it can sew with the max size top thread and bobbin thread in max. sewing thickness. That is why you see the Juki LS-341 or 1341 rated for V138 thread not V207.

Insert bobbin in the top cap and through the tension spring so the bobbin spins counter clockwise when you pull on the end of the bobbin thread. I leave about 4 to 6 inches of end thread dangling.

Place the bobbin and cap in the palm of your left hand.

With your right hand grab the end of the bobbin thread and lift the bobbin case of your hand. If there isn't enough tension the bobbin will just spin in your hand and probably fall to the floor. You should be able to lift the bobbin and case off your hand otherwise you have to tighten the little screw by turning it clockwise about 1/8 of a turn. You do not want to flat that little spring or unscrew the screw to much as if the screw comes out chances are you will never find it. Try again. When you get the tension just about right you should be able to lift it off your hand. Once you can lift the bobbin off your hand try giving the end of the thread a couple of quick jerks it should cause the bobbin to spin slightly and yet be lifted off your hand.

I forgot to ask if you could provide a photo of how you have your top threaded.

See the update I wrote in my earlier comments, up the page.

Here's how my top is threaded.

You can turn the post with pliers to get a good angle coming out of the bottom hole.

Nice update!
Did you mean bottom hole instead of bottom disk?

I corrected a typo where I ended with the word disk insted of hole.
