So that's the build from the kayfun. Im goimg to try your way this time. It looks like u tucked cotton down?  Videos I watched put the cotton through coil and point it out and up to screw the first convering over , then snip cotton at top and screw spiral top and continue to assemble.  Hows that sound? 
Sorry all questions  thanks for the help!!
		
		
	 
Yes, cotton, rayon or whatever, wick through the inside of the coil.
I use the "bunny ears" style as well, putting the bottom part of the chimney on, snip the wick ends (I use rayon, and snip about 1/8 to 1/4 above the top.) Then gently tuck it down around both sides of the deck. Then finish up. Put some juice on first, if you want. I usually don't since I'm not always sure what's going into it next 

 Just have to let it sit awhile when first filling then, before vaping.
Cotton swells, rayon shrinks. So cotton needs to just drag the inside of the coil. Rayon, use more, and almost to the  point of deforming the coil. Practice is all it takes, and different size coils take different amounts.
With your wick NOT going through the coil, there's nothing there to help in the heat transfer. Any juice will burn instead of vaporize, May have been the cause of your flamed wick, too.
