I've got fifteen of the v3.5 510XL cartos and have an two eGo (650mah) batteries, a 1300mah 510/eGo battery and regular 510 batteries.
I can't get a decent vape from these things. I get 2 drags then burnt taste.
I've been following this thread since the 'dark ages' and I think I've tried most things.
I've tried our ptb here Australia but it's different to yours. Just regular tea bag material.
Blue foam pieces sold here are too tiny, as are the black foam mod. They won't reach much more than 1/3 the way to the bottom of the carto.
I've used the original cup plug right side up and upside down. With a larger hole and as standard.
I've used the middle tapered plug, right side up and upside down. With a larger hole and as standard.
I've used it with only the mouth plug.
I've used it with no plugs at all, and tail-piped it. Burnt my lips on the third drag.
I've used regular untouched wicks. I've cut wicks off at the cup. I've cut the wicks loops. I've tried all the above with variations with these wicks.
I've tried all variations with all my batteries.
I've tried 11 different juices, PG and PG/VG mix of various ratios. They come from China and the U.S. Also tried local juice with no nicotine. I've also mixed my own.
The first two drags after the ecig has been standing are normally sensational. Then a slight burnt taste. Then a stronger burnt taste. Leave it for 1 minute, still burnt. Leave it for 5 minutes, one or two more decent drags.
Repeat.
What else can I use to make it wick better, considering I don't have access to regular ptb.
I really would like some help, as I'm at a loss as to what to try next.
I got desperate and cleaned my old regular carto's.
Thanks badkolo for the denture tabs idea. I did that, then soaked them in baby bottle sterilizing solution (milton), flushed with water, reversed Taryn spin, then bicycle pump dried.
Put all but one into a container with rice. Filled up that one. It taste pretty flat after the e2's, but at least I can take 10 or 12 quick drags if I want.
My mum (83) has been visiting and watched me do all this today. Plus the filling with the hypodermic needle. She wasn't too impressed I think

Said it seemed like a lot of trouble to go through and I explained that it shouldn't be this difficult, just having teething problems. She said the amount of time I'd wasted playing around with these today I probably should take them to the Dentist. Nice one Mum.
