Started with my first rebuildable a couple weeks ago and didn't have any problems now all of a sudden everytime I wick after a little while I'm getting burnt taste and smell I'm using a lemo ll on an Istick 50 last 3 coil builds were 1.8 1.6 and 1.2 on 28g Kanthal with Organic Japanese Cotton it will start tasting burnt whether I got it at 12.5 watts or 25 watts and only the last few days I'm at my wicks end trying to figure out why any ideas?
My first thought is how big is the inner diameter of the coil? As others here stated; heavier VG liquids don't wick very fast.
The absolute minimum I make my coils is 3mm, that's because I was always getting dry hits too.
Using the Japanese organic cotton is the right step. I am positive it's the size of your coil, plus how you're doing the finish shaping of the wick.
The following video is done on a Kayfun V4 but it's very similar in build style compared to the Lemo 2.
I followed this guy's instructions and I'm vaping like a champ. Wicks great! Takes a little longer but it's worth the effort.
Since I build temperature control nickel coils the wick had to be a little looser to avoid messing up the coil, but the principle is the same.
Try it and see how it works for you.
