Anyone else experience this oddity with a Kayfun clone?

[Forkeh]

Picked up a Kayfun lite clone, an Ehpro. I've experienced a bit of an oddity. Had a little trouble getting a coil on at first setting the coil up perpendicular to the juice flow cut out. Couldn't get it to wick. Burnt taste. Bad. But no flooding troubles. Had a revelation. Turned the coil 90 degrees so the wicks would line up with the juice channels better (easier to install that way too) and no more burning. 28 gauge wire, I don't remember how many wraps, but it's reading 1.7 ohms. Cotton wick, positioned the wicks nicely, Fairly voluminous.

Anyway, primed the coils conservatively, filled her up from the top (the juice I wanted to use had too big of a top on it to fill through the screw hole), and gurgle gurgle, massive flood on every draw. Doom. Booooo. I had an idea this would happen initially with top filling but no matter how many times I blew it out, the very next puff would flood. Anyway, I blew it out one last time so it wasn't dripping everywhere, and set it aside because I was tired of messing with it. I come back to it two hours later, intending to rebuild it, and suddenly no flood. Perfect vape. No problems what so ever.

What happened? Do these have to sit for a while when you fill from the top?

Top filling Kayfuns is doing nothing more than asking for troubles. The coil positioned where the ends point right at the juice channels does wick and function better. Coil height can also play into flooding or dry hits as well.

Thats how I position my coils. I cut the cotton just so it hits the deck and I smush it up against the wall. Have had no trouble doing it that way.

where did you hear about setting the coil perpendicular to the juice channels? I have never heard of anyone doing this with a single coil

Interesting stuff!

I'm going to guess it has something to do with the wicking. All that matters is it's working great. I have to top fill my two clones otherwise they leak and haven't had any problems for a couple of weeks now.

That was a 2ohm coil
I highly recommend 1.6ohm to 1.8ohm.
Lower (for me) is too hot, higher is too cool.
I generally sit around 1.6. to 1.7ohm.

That should be a 28ga 9/8 wrap, roughly.
Also, make sure the coil sits high off the air hole
too close and you won't get enough air, too high and it may not air properly

I raise the bottom of the coil just above the head of the post screws.
Make sure the coil leads are coming from the bottom, not the top of the coil
Make sure the leads are not touching the heads of the screws if wrapped around
use the flat head screw driver to move them away or you will create a hotspot.

Once you have the juice topped off, screw the top cap on just far enough to catch the threads then flip the whole thing upside down to finish screwing the top cap on.

It should reduce flooding by a fair bit.

HCigar top fill, no leaks. EHPro light + top fill= leaks. Bummer!

Okay, I can see people being to lazy to purchase a proper filling bottle or syringe for a 3.1 and filling from the top.
But hey, you deal with the results. You either learn to do it trick and quick to minimize a chance of flooding it or you make a mess.

Other kayfuns - Lite/plus, V2 - Top filling is just plain lame. These have a proper fill hole on the base and it is the only way they should be filled.
Anyone thinks top filling is smarter thinks they know better than the designers and I highly doubt that is accurate.
Heck, many people don't even know to leave a Bubble in the tank to set proper negative vacuum.

That is not always true, I have attempted to fill with a syringe, the issue is, when you push the blunt tip into the hold there is a tendency for the surface area of the trap to close off the end of the blunt tip needle preventing the ability to push the juice in. If you try turning it a bit, some times that trap will close and juice will leak all over. the concept is solid, the execution is not perfect. Stepping off your high horse though might be a good idea.
