So, some issues are emerging: In some cases I experienced flooding after filling it. After a bit of research I suspected that the JFC actually pushes juice into the chamber when closing it. Think about it, it makes sense: It makes the tank volume a bit smaller, so the juice has to go somewhere, which is a) into the tank or b) into the chamber.

Today I tried to:

1) Close the JFC.
2) Vape it dry.
3) Opening/closing the jfc repeatedly about 5-6 times (with the top cap closed).

After that I had juice pouring out the airflow holes.
Having had the tank in my hands this doesn't make sense. The JFC only moves the inner chimney, shouldn't have any effect on the volume of the tank.

Do you still have the o-ring at the base of the deck?

Well, as that inner chimney moves down it does occupy volume which otherwise is up at the drip tip. I will try turning it upside down when closing the JFC, AND burp it after filling, and we'll see what happens.

I do have to do this on my Cthulhu MTLs. But I'm a few tanks in on the Skyline and it's dry as a bone.

Are you leaving a bit of headspace?

When I fill? Not really. Maybe I could try that.
I see the air as the spring (gasses being compressible, liquids not) the spring can absorb some of the positive pressure that results from filling. Obviously as the level drops the spring expands to resist the negative pressure of you sucking...

I'm filling to just below the kidney holes...

The MTL, has a design flaw! the JFC holes are in the threading, & will not make a proper seal.
The work around is turning it upside down to close the top cap after filling.
The SkyLine is working well for all of us, so it could be mrjohs wicking?
Thats were I would start looking any ways :)

I always leave 8 to 10% free space in any tank when filling.

Good advise :)
I have inadvertently filled mine to the top on the second fill & still had no flooding/ leaking issues :)

Yeah, it's weird that it seems to be just me having these issues. At one instance I wicked it too tightly so I was having (almost) dry hits. Still flooded.

I'll try burping and turning upside down when closing jfc first, then if that works out I'll try without doing that. In any case I'll leave 8-10% of juice space free.

Thanks to all of you for advice.

    Double check your O-rings with a magnifying glass if you have one, they may look good to the naked eye but could have a hairline crack. China is not known for great O-rings.

    Again Great advise :)
    If it's not the wicking it's more than likely a vacuum leak! caused by a bad o ring or some thing of that nature :)

    I´ve read the following under a youtube review

    of this clone:



    I think he means sharp edges? Did anybody experience sharp edges anywhere?
    The "darker liquid seeping into the tank" effect I also noticed on my Merlin RTA, can sombody explain what exactly happens here?

    K.


    Yes that's also present in the Merlin and other atomizers. What is happening is juice coming in from condensed juice on the inner part of the chimney. It's darker because it has undergone oxidation.

    I bought the bullet and bought one. I very rarely buy clones, most of the times to check if it's worth buying the real one. However, with me vaping less nowadays and with it being out of stock and so expensive at the same time, the clone was just so attractive.

    Maybe if they decide to come out with an actual 2ML shorter version I will buy it.

    Both of mine arrived in great condition i have only built one and i am using the larger air disk with a .5 316l spaced 26g build for temp control 420f 25w and the vape has been spectacular so far nice saturated and very good Flavor. I am super impressed and ready to try building my other one for a MTL setup

    Hi,
    I wonder if any fellow MTL fan already compared the flavour/draw between the single 1,5mm insert and the next larger one with two 1,5mm holes... I´ve learned that 2x1,5mm holes are actually equal to a single ~1,8mm hole if airflow is compared.

    My assumption is that the two hole version may actually give better flavour because the air can flow over a larger surface/area of the coil, "capturing" more vape, while giving only a slightly more open draw...

    Will try myself when it arrives but for now pleasant anticipation is all I have ;)

    Thanks,
    K.

    I haven't experienced any flooding but I do get the dark juice. Still performing really well so I don't pay any attention to it. I get the same dark juice in some tanks too.
    Dark juices are just leaching from the wicks the build up leaks back into your juice it happens on many of my other RTA,s if change wick it stops until starts to gunk again.
    Thats all it is , as it dilutes down the darker gunk on the wicks from previous juices

    Ive also no sharp edges or leaking at all ,
    Even when i over fill it just squirts juice out from top cap as i screw it down.
    Never from bottom ,due to me sealing it ,
    by screwing jfc shut down , upon opening it (jfc) Airbubbles rise as it wicks to the deck
    but never leaks out of airflow ,
    I'm guessing its totally down to wicking ,
    mine wicks fine.
    Vapes very well massive amount of Flavours
