That is strange. Something has changed, though.

Occasionally, I get a bit too much wick, and get dry hits.

Have you checked the condition of your o-rings? Also height of coil. It is also possible that there is some crud on your coil, that may not be visible to you. If all of the above are ok, I'd suggest wrapping a new coil.

The KFM is new, but I did look over the o-rings this morning. I didn't want to make new coils, yeah, lazy.. (not really, just a Mom with a thousand things to do) But I will. With micro coils do you have to change coils more often than regular ones?

Hey all. Having some issues with wicking on my KFM and KFL. This is a new problem, as I've had my KFL for a few months. I'm having to prime it throughout the tanks to keep from getting burnt hits. Here's what I've got going.

KFM- 1.9ohm; 1/16th micro coil; P&C yarn with 1 strand removed. I've tried lengthening wicks, shorter wicks, pressing wicks to sides before I put the evaporation chamber on.

KFL - 2.0ohm; 5/64ths micro coil; P&C yarn full strands. Again, I've tried lengthening wick and shorter wick. Before this week, I just trimmed the wicks to reach the deck, stuffed them down and vaped away.

All juice is 70/30 pg/vg. I have been using new (to me) juice from Ahlusion in both.

I get a great 4 or 5 hits, then it starts to taste burnt if I don't prime it. Anyone have a clue? I'm at a loss.

Gasp! I don't recollect you mentioning the highlighted variable when I asked yesterday.

Are you vaping Ahl's NET's? They could be just that much different from HHV stuff that they're not working right. I've had that with NET's from a different vendor.

Try this: Move up in size.. go to the 3/32 coil but retain the same wick size (P&C yarn full strand). The juice may be choking the 5/64 wick/coil combo. I've had to do that for the gunkier stuff and also remember that you will still have to change out the wick every tank full or so.

Is Jerms around? He vapes Ahlusion stuff, and may have more insight into the matter.

 

[76bridget]

No, no NETs Dusty.. Sweet stuff tho, if that matters?

and I didn't mention it because I didn't think it mattered as the pg/vg ratio is the same.

All juice is 70/30 pg/vg. I have been using new (to me) juice from Ahlusion in both.

Bridget, are you sure it's 70% pg? Ahlusions lists the ratios in reverse, vg/pg instead of pg/vg, so if your bottle says 70/30 it's 70% vg.

If that's the case, if your juice that was working well before was high pg that would explain the slower wicking with high vg. I vape a lot of 50/50 and even up to 100% vg with no issues in my KFL, but I also prefer a tighter draw so I have tape over half the airhole. That tighter draw increases wicking.

If you don't want to change the draw, you may need an alternative wick and coil set-up that wicks thicker juice better.

Yes I'm sure, it reads 30VG/70PG on the A+ bottles.

The 3/32" coil in one of my KFL's is 6 weeks old.

I have one that is atleast that old too. The micros/minis, whatever, far outlast a standard wrap coil.

 

[Akdare]

On the KFM, I do have to do a dry pull occasionally, as the distance between the wick holes and the side of the tank is very narrow.

 

[Jerms]

Gotchya. Well then... no idea, same ratio should be wicking the same. Luckily I haven't had to troubleshoot any issues with my KFL yet.

 

[Dusty_D]

Dad-gummit, I was sure that the 70/30 would be the issue. Bridge, same ratios or not, juices from different vendors can have subtle differences depending on the extraction methods etc.

Try the larger size coil as I mentioned above, and see if it makes a difference.

One benefit of preferring a tight draw.. no matter what I put into my KFL I only get one dry hit, when the tank is empty.

That is true. I do find that the air control screw is quite sensitive. A quarter turn may be all you need to tighten the draw enough to improve the wicking, while still making it airy enough for you. Worked for me, YMMV.

Bridget if these are the same coils and you didn't have issues before, after a dry burn a) check to ensure the connections on your post are snug b) lift the coil slightly and ensure it's over the 'airflow'? hole I had problems last week with very harsh hits and burning my yarn, adjusting the coil fixed it.

No leaks or gurgles doing that, Jerms? if you're consistently pulling in more juice.. it's gotta go somewhere right? Or, are you a "high heat" vapor that goes through juice like mad?!

I did lift the coil a bit on the KFM this morning.

I will take some pics and post them when I tear them down tonight and see what you all think. Thanks for all the suggestions.

Occasional gurgle, especially with thinner juice. Goes away quick if I take a longer pull or tilt my mod up to not allow more juice into the chamber for a pull. That's fairly rare though, I have a fair amount of heat going on, 1 ohm 28ga micro on a mech. My wick stays nice a saturated, which seems to give me better flavor.

I think that even though more juice is being pulled in, what doesn't get sucked up by the cotton gets pulled back out of the chamber from the vaccuum effect, preventing problems from too much juice.

 

[76bridget]

Ok, one side of the KFL wick was too short. And the mini coil too high.

Here are my coils, before and after.

I did both with 5/64ths, as I don't have a larger size here. 30g, 1.7 ohms. Going to put HHV in the KFL, A+ in the mini (as that's a bigger size than I had in it before). Any suggestions before I wick and fill?

everything looks good there. most of the time the coils are fine which seems to be the case here. you said you checked the O-rings because if the top chimney oring is damaged or is not seating good that can create an issue. maybe take it out and turn it around just for the hell of it. also have you dropped or jarred the device lately, I remember dropping mine, this caused the threads to move which may have caused a pressure issue. I just unscrewed the plastic tank and re threaded and all was fine. don't know if this is the case, but a possibility. other then that its usually a wick issue. its definitely a fine line, sometimes I can re-wick 10x's with no issues then all of a sudden I have issues where it takes a few times to get it right. good luck

Like I said Bridge, disassemble your KFs, rinse clean, inspect for orings, build a new coil (the same as you always do), rewick, reassemble and see what happens.
