Kayfun Prime problem, please help

[vapdivrr]

Well being your in Poland , it can be the Colder weather or your juice, so I think 1.5 or 2 turns is ok. For me being in florida, probably makes my juices thinner, thus less turns. Your last wicking looks spot on to me. The older pics do look a bit to much thru coil, but seems the new way is slightly less. I would always keep exactly the same amount thru coil and from there try slightly different amounts in tails. Now that you seem to have the correct amount thru coil, if your getting leaking, it could be your tails aren't quit reaching ledge bottom or trimming slightly to much off tails....hopefully your getting close, as your having good luck in this last build. I do prefer 26g myself, as it's just a more ridged and longer lasting coil. I personally only do 6 or 7 wraps, and spread them out slightly more, but I just like a faster vape.

Regarding the liquid control - I dont see any bubbles when I do one turn only.
I have to do 1.5 -2 max and I dont have any dry hits then but one turn I tried twice and both times I got a dry hits.

I need 1.5 to 2 turns as well, but I'm also well north of Florida. I think your wick looks pretty good. I don't think I'd make the tails any longer, although I can't be sure I'm interpreting the pictures correctly. I use a screwdriver to push them into the well, and I can tell by the feel if they're the right length. As vapdivrr says, if they're too short they won't wick well, but if they're too long they'll jam up the well and that can interfere with the juice flow. If they're short, you'll be able to feel the screwdriver hitting the bottom of the well. If they're too long, you can sort of tell they're bunching up and there might be a wad of cotton under the screwdriver.

The only thing I might change is the thickness of the tails. They look like they might be a bit full so you could try thinning them just a bit. Then again, if it's working for you now I wouldn't bother changing anything.

I get the same feedback when using my blunt tip needle when arranging my wick tails in the ledge. It's hard to explain, but like you said, you can feel it. If they are a bit long , you get that slight bunch feeling, and if not long enough, it feels to open down there.....I have always felt that to much jammed down there mutes flavor and wicking, but not enough and you can get seepage.

Thanks guys,
I think I`m almost there. I got a leak every 3-4 days, under the plate which I`m still not sure where is coming from(meaning what I`m doing wrong at that moment) but I ll keep in mind your screwdriver/needle advice. I think I know what do you mean.
I`m trying to cut the length of the tails up to the first black o-ring when I fold the tail on the deck
(as on one of the picture) .This seems to me like the good length to hit the bottom of the well but not sure. Once folded into the well it might be shorter/longer?.
Would you say this is a good approach?

BTW we have a very nice spring in Poland now. It`s more of a Florida kind of weather
We are hitting almost 30 Celsius degrees at some days! My profile picture is from 2 weeks ago by Baltic sea!
Thanks again for all your help!

Looks about right to me

With a Kayfun, I think, more important than the exact length is that it just makes contact with the deck. So if it's a little short, it won't have much of a shoulder at top. If it's cut a little longer, shoulders will be higher. That one looks close, but like it might have a pretty small shoulder at top. After a while, you'll begin to get a feel when tucking and pushing it down into the well.

 

[vapdivrr]

That's how I measure my tail lenghts but it depends on your coil height. I set my coil height at 1.3 ish mm, so the oring is spot on for me...as brew dog mentioned, you possibly could be a smidge short perhaps because of the slanted angle in which you are holding the tails. You can make the ledge, but you might not have any shoulders doing so. So it doesn't hurt cutting perhaps a smidge longer and if it is perhaps a little long, you can push up the shoulder slightly. You just don't want wimpy shoulder, as if the wick comes out from coil and angles down right away. You definitely want the shoulder to come away from coil and make a nice 180 degree turn. On your next rewick, keep that same amount of cotton thru coil you have in current build but maybe don't trim the tails (only trim lenght) and see if that doesn't stop the seeping. It's hard for me to say, because I use rayon and I have to trim bulk off of my tails, but with cotton and a fairly small diameter coil, and not inserting a lot thru coil, you might get away with no bulk tail trimming. If that stops seepage , but now your getting dry hits more, then perhaps it's something in between what your trimming now and no trimming?

I don't have any dry hits whatsoever now, it`s pretty good recently - thanks to all your help.
I`m trying everything that you mentioned and I have also watched your video vapdivrr .
It is the best and most detail explanation of the Prime I have found.
I actually trimmed the tails the most yesterday(same as you on your video) and so far is very good.
I ll have a look how the wick look like tomorrow morning and taking from there.
(I have one side always more dark so as you have explained in your video -I still do the wick wrong)
I think it was worse when I did not trimmed the tails at all but that could be because of the lengths. So it is still the learning curve for me.
I ll try the tails slightly longer next time as you and Brewdawg suggested.
So far it is good but I do get a leak around the 510 plate every third day or so.
I wonder if this is because I don`t close the juice control over night?
I got the leak twice at the morning so I wonder if this has anything to do with it?
I wonder when I ll become a Prime expert ) .... and I thought I knew everything!

Do you have any big pressure or temp changes? I know I will get some leakage in the summer here, going from a big temp differential, like if I leave my tank in my car for a while then take it into the a/c. Also if you change in altitude some....my video is with rayon, so there are slight differences in wicking. I probably add slightly more rayon in coil then cotton and probably trim slightly more off tails then cotton.....you can try twisting the wick while inserting, by doing this, you don't get that , one side of the wick more dense then the other, creating a darker side. You can twist the wick, insert, then kind of untwist....there can be another possibility, the seating of the insulator. Your going to get liquid obviously on and around the deck, and if the deck or insulator isn't perhaps seating correctly, maybe juice is leaking under it? Have you taken the deck and insulator off and inspected them? Then seated them back and re tightened?

I don`t have any temp or pressure changes since I have my Prime.
I did remove everything and checked twice already - all seems fine.
However I think you were right in the first place and it looks like doing the wick properly is the key.
I don`t have any leaking since 6-7 days ago so I think I`m there.
I`m aware you were doing the wick with rayon so I keep this in mind when I`m doing mine with cotton, however since I trim the tails a bit more than before- it`s ok.
I have taken into account everything you guys thought me and it`s looking promising!
Thank you very much once again for all your time!
