troubles with cb3500 threading on upper tension

[TonyGreen3455]

help needed
a bit strange issue, I can't even describe in which area exactly - the threading, the tension or machine itself.
cb3500 clone. the thread 207/15

the thread, which is initially threaded as usual (via correct way, I hope) when sewing, jumps out of the upper tension. just comes out from between the plates and all the tension disappears.
was trying different ways to thread, screwing tension/plates up - all the same. thread 207 does not want to be in between the plates when sewing. 
imho most logical way to fix it - to put extra thread guide after the tensioner, but there in no any hole/screw to connect it at all. no any way by the design.

with a thread 277/10 no such problems, everything was fine.

so, where I'm wrong?
or it is hardware issue and smth to be replaced/fixed/installed?

any advises welcome

TonyGreen3455 You should have a spool pin in the center on top of the machine,run the thread through 2 of the holes & it will give enough pre-tension to hold it.

you mean - this one?
threaded as per video - through single hole, but will try it for sure, thank you!

On your top tension disk, is your thread seated completely in between the disks.

In the picture it looks like it just sitting on top instead of it sandwiched in between. Give a good tug down so it sets in.

That is the culprit . . . 

I take my 346 thread thru the other side of the post . . . wrap once around it . . . and come thru it again starting on the same side as the first thread.

It was a guess . . . first time I threaded my 4500 . . .  and has worked perfectly for the last 3 years or so.

Try it . . . I think you'll like it.

May God bless,

Isn't his thread path thru the top tension disc wrong? 

Shouldn't it look like this? Granted this is a Cobra class 4, but I think the threading is the same.

I though the same thing so I looked at a couple youtube videos and for the Cowboy it's different than the Cobra, based on those videos.

Ok sorry. I thought they both used the same threading path.

those pict with a thread on the top taken after that. 
at the beginning put it in between plates completely down - it is why a bit surprised with such issue. 
confused - thread itself is either too thin or slippery  

many thanks to all for your opinions - will try it

followed all recommendations  and on top of that moved thread guide before the upper tension a bit down, just below the axle of the tension itself - see pict. 
very happy with a result, whatever it's a right way or not. 
many thanks to all again.

That's the way it's done on the Cobra but if it works it MUST be right lol.

The funny thing is that when I saw this thread I found pics of how the Cobra is threaded and mine was totally wrong. I don't know how I was sewing anything with how wrong it was but it worked.
