Hey, been using the forum for a while to help solve issues, but I finally found something that I can't seem to find a straight answer to: I have a russian 91% and when it comes to the wick, I don't quite understand where it needs to go. Seems the majority of people say to put the wick just above the fluid channels, bit not covering them. When I bought it, it had a pre built coil with wick already installed and the wick was in the fluid channel. So time comes for my first rebuild, make a 1.2 ohm micro coil with organic cotton wick just above the channels, screw everything together after priming the wick, fill up the tank from the fill hole on the bottom, and everything works great... until I set it down. It starts leaking out of the air hole. I tried three different things with the wick and the only thing that has alleviated the problem is actually putting the wicks into the channels, which seems to be reducing vapor. So, am I doing something wrong to get the leak, or is this just what seems to happen?
Russian 91%/ Kayfun lite: Wick in or out of fluid channels?

Russian wick in kayfun wick out. if you got a leak check all O rings as you most likely have a pressure leak and the tank is getting a little air from somewhere. also make sure to put some ejuice on the inner O ring that connects to the chimney it seals better that way.
with my Russian I only get air hole leak if there is air getting in somewhere these tanks hold juice by pressure in the tank.
check out "suck my mod" on you tube he did a review on the black Russian 91% v2 recently and it has a lot of good info in that tutorial/review

The wick should never be in the fluid channels. This will stop up the flow of the fluid causing dry hits. I don't think it would cause leaking. Leaking is usually caused by a bad oring or filling the tank too full. Filling the tank to full causes an unbalance in the pressure. Anything interfering with the pressure inside the tank will cause a leak. There are several good you tube videos that can help. Just go to you tube and search Russian 91%.
Good luck.
Good luck.
This is how I wick my KFL+ with cotton. Please excuse the caterpillar coil, it was one my first. It looks bad, but it came out to around 1.6Ω, as I recall, and vaped just fine. 
ETA: Regarding the leaking...have you tried holding a paper towel over the airflow hole and gently blowing through the drip tip?

how hi is your coil over the air hole in the vaporizing chamber??? I find that if the coil is too close ( less than 1mm) it allows juice to run down the airhole and dribble out of the air intake on the side ( exterior) of the unit... I put my coil approximately 2-3mm above the air hole... no more dribbles....
My coil is about 2 mm above the air hole. I think the problem is my wick isn'tthick enough, which is allowing too much juice to enter the chamber and flooding the tank. Next time I make a coil I'm going to try to make a slightly larger coil to allow for a thicker wick. Aside from that, I've noticed that the o ring for the chimney is up where the drip tip screws in, but in youtube videos I've seen that it is in a different place.

I do this after every re-wicking, because I get a bit carried away with "priming" the wick as I get it all situated, to prevent the dreaded dry hit. Once I do the blowing-out thing, I *never* have any kind of leak from anywhere. It works like a charm. Note: someone told me, and I've found it to be useful info, to hold the thing upside down, so the airhole is above the tank, when doing this.

The wicks should never be in the juice channel on either one. I have four of both and I set them all the same. Coil approximately 1.5mm - 2mm above the air hole. Wick just touching the top of the deck. Once the chamber is in place then I push the wick against the inside wall (closest to the coil). When I first got them I did have issues with leaking, then dry hits, then it leaked, then dry hits because I kept reading less cotton is more and I was afraid I had too much. Then I doubled the cotton I was using and BAM, never have a problem now with leaking or dry hits. You want to have a enough cotton to cause resistance when pulling it thru, then work it back and forth until it moves freely. Trim to touch the top of the deck. Hope this helps.
I've only had a leak with one out of five Russians, and that was due to an o-ring defect. Other than that, they've all been as water tight as a duck's .....
Four of them are stored horizontally. One of the four (random) goes to work with me every day in a Cigar Caddy. No leaks in transport.
I don't obsess over the fluid channels, as I rarely vape with the unit close to vertical. As long as the evap chamber side of the channel isn't blocked, you should be good.

I saturate it because I want to test the resistance after it's wicked and my mod "fires under load," which would toast the cotton if it isn't wet.
I agree with you. That's how I set mine up with the cotton wick snug in the coil. I never have a problem with mine. Also I use a drop of juice on each o-ring to lube them up before putting the tank together.
That too, of course, but even after I do that, I put a few more drops, because dry hits are just so horrible. Now and then I manage to not flood it, but usually there's a bit of excess; the blowing-out trick fixes it very quickly, and then never a leak. God I love kayfuns, even my Tobeco clones are so far past anything I used before, for quality and especially performance.

How are you filling ? I found that when I fill from the top it inadvertently will cause leaking, and I've got to do the paper towel thing a few times to get it right, using the bottom screw almost never, the wicks just touching on mine also,as for the dry hits try looking at rayon, I'm also planning to get some.
This is important! I lube the o-rings with juice every time I re-assemble, and have no problems whatsoever. These things love to be air-tight.
I have a russian 91 also check the oring on the top of your tank, it fits in fits against the top of the chimney, I thought it went farther down on the chimney my first build and leaked very were!!! got if figured out thought an got the oring in the resest groove now it works wonderfully
After some trial and error I went from leaking, to leaking only when on its side, to no leaking what so ever. From what I read, it seems the fluid channels on the russian are a little too deep, which is allowing too much juice to enter the chamber, flooding it. I placed an o ring around the base of the chimney to restrict the juice flow a little bit, made a 2mm inner diameter coil which allowed me to use more cotton and keep it fluffy (before I was having to roll and twist thehell out of the cotton to get I into the coil) and have it pressed against the inner wall just above the juice channels.This has alleviated the leakingproblem completely for me. Thanks everyone for your advice
