Ok, so I'm using a stock joye 510 (no HV, no LR attys), using a double folded frayed ptb filler. I fill the cart till it's a few drop from the top and slowly but the ptb in till pushed down all the way and fulling saturated. I had only minor flooding issues, didn't even have to blow the atty out, just wipe the threads out and it hit just fine. I don't consider myself a heavy vaper compared to the descriptions some have given on this forum and normally wait for the atty to cool down in between hits, yet I've blown thru a cart in less then an hour and I don't understand how. I checked the ptb and it's almost dry and there isn't any pooling at the bottom of the cart so I know that I'm actually vaping the juice and it isn't being wasted (aside from the minor flooding I mentioned before). I've seen people say that they can vape rather heavily for an hour or more on a single cart and I don't understand what I'm doing wrong. Do I really vape that hard or is there something I'm missing?
