I have tried to rebuild my T3S over and over again and have had nothing but gurgling and/or poor vapor production. The strange thing is that my evod rebuilds all work fine, and the heads are practically the same except that the T3S has a longer stem. If I add less (or no) flavor wicks, it gurgles, if I add more flavor wicks, I get very poor vapor production, and, Ironically enough, a muted flavor. I'm using 0.25mm (30 gauge) kanthal and 2.5mm silica wick. Can anyone give me some tips or advice? It would be much appreciated!
