How far is your coil above the air hole? Should be between 1-2mm.

EDIT: Just re read your original post...if you got good flavor straight from the chimney, it might be an airflow adjustment. Try opening the airflow adjustment screw on the bottom.

opened it all the way up its like a straw now but nothing. i have also tried 3 more builds. i cant make these coils anymore perfect then what they are, they are all picture perfect coils, latest one is 1.8ohm. i use it on a apv. i have the coil about 2-3mm away from the hole. i mean it vapes, just not much flavor. vapor is pretty good, not amazing but pretty good. no dry hits, just not fully saturated.

edit** took another drag from the chimney and the flavor is the same diminished.

I run a 1.8 ohm 30 gauge coil wrapped around a 3/32 drill bit. I only have it about 1 mm off the air hole. The coil is perpendicular to the posts. Cotton ball wick. Be sure and not roll the cotton, it will compress it too much, in my experience. I just pull it gently until it is about 1 1/2 times the diameter of the coil. Wet your fingers and roll a point on one end and thread it thru the coil. As you pull it thru, feel for any resistance. If you do, or you see it bunching up, use some tweezers to take out a tiny bit. I cut my cotton just past where the chimney threads start. Pull the wick upwards, and put on the bottom part of the chimney. Gently put the cotton into the sides where the juice channels are, juice it up liberally. I also put a drop on each juice channel to make sure that the juice "crawls" into the chamber. Finish assembly, and fill from the bottom. Don't fill it completely full, leave a bubble of air. Give it at least 10 drags before you judge...if it's still not right, try adjusting the air screw a quarter turn and try it again.

What kind of juice are you using?

Coil looks good. What size diameter did you wrap it at? Looks a little big to me.
It looks big to me as well... and I'm curious of the mandrel size. The largest I ever (rarely) go is 3mm (7/64"`1/8"), and like you, mostly 3/32" (2.4mm) and under... all with 28 ga, down to 24 ga.

i took a drag from the chimney before filling it up and the flavor was unreal.
I can answer this particular point of interest for you. As you can imagine, this is much like drawing from a single coil RDA... while the reduction in both temperature and air flow is due to the remainder of the KF being assembled and filled.
You lose the added air flow of the wicking channels being (temporarily) open to the atmosphere, and the heat generated in the atomization chamber being absorbed by the surrounding liquid - and the surrounding metal.

When you take several long draws in a row, you can reproduce the heat, but you can't compensate for the lost air flow... even by removing the air screw.

i think the drill bit is 7/64 i think not sure. yes its bigger then 1/16. i dont have a 1/16 atm i do have a smaller one that i think could be a bit smaller then 1/16 or may even be 1/16. no markings on these dam things. i lowered the coil to about 1mm off the deck. added new cotton and now i am trying it out.

edit** same no change. :blink::facepalm:

might try and wrap a smaller coil. maybe it is too big. would the coil being to big cause these issues?

Are you sure it's not 9/64"? Like reeftivo, it looks bigger than 3mm, at least to me. Do you not have a way to measure the size... a dial or digital caliper... or even a machinists ruler?

I'm too lazy to go back through the threads - what is the resistance of the largest coil shown, and the wire gauge please? I'd like to calculate how much power is required for the coil... and if perhaps you're power balance is lacking, or, ah... odd.

Here's a chart... might help, might not.

I'm not sure that it's your problem, but that looks to be a lot bigger coil than I like to build. Try wrapping on something 1.5 to 1.6 mm and see what you think.

A larger coil is more critical of the amount of cotton used for wick. Cotton swells quite a bit and the more fibers between the coils the larger the wick is going to get. For a 1/16 id coil, the wick should have a very small resistance but for a larger coil the wick should be a little loose and allow some soak time for it to swell before vaping. You can tell if you've used too much wick by how hard it is to pull the wick out for replacement.

As far as cotton goes, I'm of the opinion that cotton treated with hydrogen peroxide is best. There's very little cotton taste that goes away within a few puffs.

Have you tried a vertical coil setup yet? You might like that better.

Edit: Looks like I need to type faster lol. Looks like you've got some good suggestions already.

Hmmm... unless there are such a thing as "fat" toothpicks, the ones I have measure between .085"~.090" - or around 2.2mm and just under 3/32"... so you're in the right ballpark for coil inside diameter. Although, for you, smaller ID, with more wraps and slightly less resistance may be better.

My "typical" 3/32" coil for a KF type atty is 7 or 8 wraps (compressed) of 28ga K A1 at 1.7~1.9Ω.

Your wire gauge is?

how tight to the coil should this cotton be? really snug or lose

28g state
Loose... a loose, not too dense roll, and a fit with nearly no drag. As I recall, you discribed your wick fit in a similar way, so I didn't think too far along the idea that it was incorrect, but... this is where your feel, my feel and 10 thousand other vapists feels may vary somewhat.

You'll find the "perfect vape" eventually. As you seem to have reasonable coil and, I assume, resistance values... it's down to wicking, air flow and voltage delivered.

For a large coil, you want it loose and give it a couple hours soak time. With a smaller diameter coil, your wick can be a little more snug and you can vape straight away, but I still like to give it at least 15 to 20 minutes of soak time.
