I believe that burning the wick on a CE2 was done earlier when CE2's were first released or shortly after that, as it was needed to help with something that I don't even know!
I also believe that the manufacturer of the CE2's changed something (maybe the wick material) and you no longer need to burn the wicks on CE2's.
Hope this helps!

A couple people told this to me... but when I got my 5 pack of CE2's.. I started to experiment... #1 #2 and #3 all were failures wicking wise, even at 3.7v (The coil was getting red hot even full of juice)
on #4 I decided to try and burn the wicks using a butane torch lighter. I torched the wicks in the new CE2 guts, dry burned the coil for quite awhile (to simulate 'torching' the wick inside the coil) I unravelled the ends of the wicks.... This bad boy stays BLACK even at 5v.. so much vapor and flavor... burning the wicks still does definitely do SOMETHING.. i don't know what but the difference was so pronounced it was unreal.
I decided to use #5 to confirm my findings, so with #5 I simply just burnt the wicks/dry burn (while they are new, without juice).. I didn't do any of the other mods I did with the last one (like replacing the fill-cap upside-down to improve wicking, which it does) just burnt the wicks..
And #5 wicked almost as good as #4.. heh.. if anyone has any idea WHY this works, please chime in.. but it does appear to work.
