I know this is going to come across as me being a smart ....., but I'm not trying to be at least this time LOL
Does anywhere on the device, box, or instruction booklet say the word Kayfun?
Then why treat it like a kayfun, no kayfun to date can even come close to a Lemowith the right build.
The Lemo and the Kayfun are two different vapor delivery devices, yes they work in a simular fassion as a vacuum fed tank and have a simular build deck.
But have you ever tried to get a kayfun to deliver a consistant quality, flavorful vape above 20w? It's damn near impossible.
Why small chamber, lack of adequate air flow, and the inability to flow enough juice to the wick.
The Lemo solved all these issues.
First more is better, 2mm-3mm ID coils seems to be the sweet spot, don't be afraid to take it below 1ohm with kanthal, I found for me around .5 to .7 single parallel 28ga kanthal worked best YMMV.
Put some wick in that coil, I've found if you are using cotton, (I use shiseido Japanese cotton) use more than you would with a kayfun, with a kayfun you would pull it through with little resistance, with the Lemo pull it through with allot resistance, almost to where you think it's too tight, it's not but again this is not a kayfun either.
Keep your wick tails away from the juice channels completely.
I built a simple tool to stick down into the juice channels while preping using a folded piece of 24ga kanthal (search a couple pages back)
Learn how to use your airflow and adjust your wattage
If you are running it at 15w with a tight draw even though it can, you may as well stayed with a kayfun you aren't doing the Lemo any justice
Open up some air flow and crank up that power, you'll find flavors you didn't know your juices had.
With the right wicking, and correct air flow adjustments you could chain vape at 100w (if you like a damn HOT vape) and the Lemo will keep up.
If you feel you are not getting enough flavor.
Not wicking enough
Improper air flow adjustment
Not enough power
As another side note not all juices do well at higher power, they taste ok at lower power and less air flow as if they were custom tailored for clero's and kayfuns
but don't do well with more air flow and higher power settings.
