I have done exactly that, and still dry hits. :(

Bronze has done some extensive testing that I appreciate immensely, but I'm not sure if we've accomplished anything...none the less, I appreciate his efforts very much.

As we speak, I have a 2nd KFL on the way to me...maybe that will solve my problems. :2cool:

Well, we verified your kayfun works Yeti. I think you'll have the same issues with the new kayfun. I have your KFL working perfectly fine with the 30ga microcoil.

because of the lack of airflow control im finding the kfl to be much more fussy with the same micro coil setup than my k3.1 and k mini...
currently using 9wraps of 28awg 1.1-1.3ohm...works beautifully on the k mini and k3.1 with airflow restricted, however getting dry hits on kfl or flooding....cant seem to get a sweet spot....50/50 liquid generally.....
any suggestions for kfl micro coil specifically?

Just a suggestion...when we talk about number of wraps and wire gauge, we should also add what our inside diameter of the microcoil is. This also makes a very big difference in resistance and how the coil performs.

yeti, if you want I could send you a coil, it will be exactly like mine, a 8 or 9 wrap of 26g wire. this coil will be ready to install with the bends already in place. just snap around the screw heads and bob's your uncle. this coil will be pre wicked with the exact wick that I use with the exact length. all you will need to do is place it just like in my photo. what do you think?

That's an excellent idea. I know Yeti's KFL will work with a subohm coil. I just don't have the wire.

Hi All,
I've run into this same problem twice in 2 days. I have everything set up correctly and the K-Lite is working beautifully, then something obstructs the airflow and the draw starts to get a little "tight," but still working ok, then with each successive drag the draw gets tighter until it is completely blocked. At this point, I try to unblock by either taking a really hard drag, or blowing into driptip, or both, then it's like all of the floodgates have opened, and the juice begins to completely empty out of the airhole. I've tried taking it apart when its blocked, and I cannot see any obstructions. Thoughts?

my inside diameter currently is a standard toothpick- LOL....my 2mm ekowool fits beautifully inside, or the rounded 1.5mm solid ekowool..both work exceptionally well in the k mini, k3.1, but not quite there in the kfl

Jon, you're sure all your segments are snugged tightly...inside and out including the chimney? Not missing o-rings? Damaged o-rings?

No missing or damaged o-rings, and everything is snugged tightly, it works great for a while, and then something blocks the airhole/drawtube?

LOL!

I have a "standard" toothpick here and it measures 2.25mm. Probably a little on the large side but even if you wrapped your coil around a tree it doesn't matter in the final analysis if it's working for you. :) Most people get a drill bit. 5/64ths = 2mm. 1/16th also works good.

I just did a 9 wrap micro coil using 26 awg and a 2mm wrap. It's performing perfectly at .8 ohms. No leaks, great vapour and no dry hits.

Yeah, I checked that, normal size gap, bottom level with post screws.

I can't think of anything that would block your air passage other than juice. So it is either getting in there from your coil or wicks or there is some kind of condensation thing going on. I'm assuming your wicks are clear of the air hole too?

I vouche for wick issues as well if coil separation is adequate. If there is to much wick (assuming cotton) around the coil it will expand and create a blockage. Also if there is TO much wick around the deck blocking juice flow it will feel like the air draw is a bit restricted. Pulling hard on it will lift the wicks off the deck with the extra pressure and you'll open the flood gates into your atty as you described.

so yeti, you have done a sub ohm micro on the lite that didn't work right? what diameter, gauge wire, resistance, and wick material was it?

Yes, I have - following your great micro coil video(s)! ;)

I've used 24ga, 26ga and 28ga - all wrapped on a 16ga blunt tip needle and using cotton wicks from sterile cotton balls. My preferred resistance is in the .7-.8 ohm range but I've gone higher just for testing.

Wick is generally not too snug in the coil, no shoulders, with tails just a smidge longer than it takes to reach the deck - but, I've tried many different wick configurations/lengths, all with varying degrees of success but with the same ultimate outcome - dry hits after a few good vapes.

I think it's a wick issue as well, either too much, too short, or too long. Do you position the coil perpendicular or parallel to the screws? I think that might have been my problem, I had it parallel, trying perpendicular now. I'm using a cotton wick by the way...

The best way I've found is diagonal coil with the wicks going down each side of the deck and across the deck floor on each end.

That's an awesome offer, but probably not necessary....like I've said, I'm no noob at coil building. I've been rebuilding for about 3.5 years, and thanks to the plethora of micro coil vids out there - and building micros myself for a few months now - I think I've got it down. In fact, my usual KFL micro looks exactly like your pics above.

All that being said, if you want to toss a coil in the mail for me to try it would at least eliminate one more variable from the equation. I'll PM you my mailing addy.

Thanks!!! :)

Well, we verified your Kayfun works Yeti. I think you'll have the same issues with the new Kayfun. I have your KFL working perfectly fine with the 30ga microcoil.

Not to belittle your (extremely appreciated) efforts - but we don't know that for sure...yet. :)

That's an excellent idea. I know Yeti's KFL will work with a subohm coil. I just don't have the wire.

Maybe Vapdivrr's coil will solve the mystery! But I'm not expecting it to work any different than the coils I've built that look exactly the same.
