Ok ... so based on these pics, I would say that this is a COMPLETELY DIFFERENT MANUFACTURER*1, but the same supplier. These were not machined in the same factory. The supplier is using a new "source" but is re-selling this to vendors/FC as the same product, but it is not. Shame on them for not notifying Focalecig that they had changed sources for this Kayfun.
The issue is now clear, but now, how to fix it?*2 I had asked Haku if he tried putting the o-ring on the outside of chimney after it is screwed on to the base, which I am thinking may allow more juice flow to the wicks because the o-ring is no longer blocking the wick, but still keeping the vacuum in the chamber by blocking it off from the outside, as opposed to the inside??

That's what i was thinking when i got those... like and who are you? you are not 12113, no way.

Lets take old atty as standard for measurements (we can't compere them as old and new because it's obviously different atties).
Base. Juice channels are pretty close with old atty. How i see it. Purpose of o-ring has nothing to do with a temp to fix juice flow.
Top cup. Grove for o-ring is 0.5mm higher then on old one.
Chimney. It's 1mm shorter then a chimney on old one.
So, how i see, purpose of that o-ring is to keep chimney higher, as you may see from the last picture. And it will be a great solution IF at the same time o-ring will not block juice channels. If take that o-ring off chimney immediately going down what unseals top cup/chimney connection.
I see only one solution what will fix this atty solid (without playing with it every time) - get longer chimney (at list 1.5mm longer then it is right now), what is brings me to the point - need just get nano kit.
Or (not sure) try to put o-ring in middle of chimney what will make it longer (higher) but ... again but, as you can see from pics, they made all of the threads shorter, so, with o-ring in between 2 parts of chimney, it will be not possible to connect chimney together.
Update for issues with 12113. Doris still investigating and having a conversation with there's supplier to find a solution. Also she said they will have to stop selling 12113 till they find answers for there's question. She is on weekend till June 24th. I will update when she is back.
Edit:

He-he, you are lucky you got chimney what high enough to make a good seal with a top cup. main doesn't.
