Kayfun question

[alarsen77]

Hi guys I have a kayfun 3.1 clone. It has been working amazing for quite a while now but all of a sudden when the juice gets to where you can see it half way down the clear window it starts gurgling/flooding just a little bit and also drains that fluid quite quick. It doesn't leak out the airflow at all. I am confused cause it vapes awesome up till that point and has never done this up till now. What could be the problem why does it start flooding half way through the tank? I have read through the kayfun flooding threads but nothing addressed this specifically. Also it is a .8 ohm coil that is sitting directly above the air hold about 1-2mm up and it is wicked with rayon packed pretty good but not too much.

Be sure and check that you have a good seal. That's all I can think of at the moment. Hopefully someone will chime in that's had a similar problem and solved it.

 

[alarsen77]

I am pretty sure the seal is perfect I don't notice any air leaks at all. Maybe I will replace all the o rings just in case.

the only time I have gotten slight gurgling was the times where I had a little to much mass to my wick tails. do you trim tails? especially with rayon(because it does require more into the coil) the tails can become a little to much(compounded if one is using a fairly large diameter coil). worth a try (if your not currently doing so) to trim just the tails.

 

[alarsen77]

What do you mean by trim the tails? What I usually do is pull the wick through the coil with about 1" on either side and pull it up through the chimney and screw the chimney down then trim it to about 1/4" above the chimney and stuff the wick down above the juice channel it's not packed tight is still airy in the chamber and sits above the juice channel. I don't put wick in the juice channel at all.

what diameter coil are you using? what I do is feed the rayon thru and once I have the length I want, I then reduce the part that's not in my coil, just the tails. basically I take a scissors and trim the tails so they are not so wide and fluffy. now being that your just going straight down to the channels and not angling the tails along the ledge on the lower deck then perhaps this might not be your issue. for people doing angled coils, and placing the wick tails along and across the ledge, a full wick tail can be to much. here is a pic with cotton of how I do my tails, if I were to use this method with rayon, the tails you see would be increased, and perhaps would be to much especially if my coil diameter was even bigger then this 1.8mm. so if this were a rayon build I would reduce the tail amounts. but like I said, if your just going straight down to the lower deck then this issue of too much tail amounts may not be your problem.

Ok my coil is not angled like that and it is also bigger diameter I don't remember exactly what it is to be honest. I will have to mess with my wicking strategy again

if this paste doesn't work, check out post 5167 in the rayon thread, it shows how much the wick tails are trimmed. like I said, for me anyways, the only time my kayfuns ever gurgled was when I had to much wicking material in the channels so if you aren't successful with the orings (cause it could be a seal issue) then perhaps try reducing the tails

 

[Nomoreash]

I agree, sounds like to much wick. I've personally settled on a 5/64" dia coil for my kayfun builds laying the tails on the deck along side the wall much like pictured above. Tried going larger and had occasional problems with it wicking to much and flooding.

If yours has adjustable airflow you could also try loosening the airflow screw a bit, that will help against pulling to much liquid into the chamber.

Also as said above it could be a bad seal but that would probably be showing up all the time and not just when the juice starts getting low. Anyway, that's an easy check, just put your finger tightly over the airhole and draw, you shouldn't be able to pull any air through, if you're getting a good flow of air with the airflow hole covered you've got an seal leaking somewhere.

Maybe check your o-rings

 

[DaveP]

I second checking o-rings. There's also one under the top cap that seals off the air tube to the cap. It's easily missed. I use the full length clear tube and remove it here and there to recoil or replace the wick. Doing that eats away at the o-ring and I have to change it periodically to prevent leaks. All it takes is a chip in the rubber and you have a small leak.

If it's leaking juice, then you probably have a vacuum leak somewhere. You can check that by covering the air hole with your finger and taking a draw without firing. It should be so tight that it causes juice to be drawn up into the wicks and that's evident by the air bubble you'll see after you do it. If there's a leak, you can tell.

This link is a guide to the best coil and wick design I've found so far.

Yeah I checked for air leaks that way and there are none. I have to cover the air hole and the screw that goes in otherwise I do get a little air leak out of the airflow control screw

 

[alarsen77]

Alright so after messing with it a bit and checking for air leaks by covering the air hole and pulling on it and not hearing any air leak. I decided to just replace every o ring in it and I noticed the one in the top cap that grabs the chimney grabbed a whole lot tighter than before and now I don't get any juice spatter through the mouth piece anymore and no flooding anymore. That o ring must have been shot.

Have you checked to see if the drip well is full. I've had that problem. What is probably happening is the wick tails are moving and the juice is going through the air hole and into the drip well. The air hole. And the drip well are connected.

It was the o ring in the top cap see my previous post

I saw it after I posted my option. Glad you got it fixed

It's cool. Thanks, I am too it was driving me nuts. I can't wait to get my orchid clone from my local Vape shop next week.
