Ok so im still a bit new at this but i had made a thread recently regarding my fluxomizers from gotvapes and clearo cartos from nhaler. Im still on the fence about the clearo cartos but am trying to remedy the issue with them so no need to go into it. As far as my fluxomizers...when i first got them i HATED them. Horrible burnt taste even after cleaning and dry burning. Well i think i have figured out the issue. Obviously i took the fluxo apart...i noticed that the rubber seal inside is nothing like all the videos ive seen on the gotvapes site or on youtube. Its a little rubber notched gasket with a little rubber tube coming up...thats it, no other seals. i had set them aside cuz no matter what i did...i could get that burnt taste to go away. Well after playing with it for a while tonight out of boredom...i noticed that wjen i put the drip tip on in really presses on that rubber gasket too hard, possibly making it too close to the atomizer and creating a nasty taste. So i figured what the hell...if i break it no big deal. I decided to take that little gasket and trim down the tube to half the length it was...and i also trimmed the wicks down a bit to accomodate for a little more juice. I gave it a good dry burn, reassembled it, put the drip tip on which now doesnt press down so far with a shorter tube, filled it with some HPNO juice and bam!! no bad taste!! so i went ahead and did it to all 5 of them testing them with different juices afterwards. Problem fixed!! Great vapor and no bad taste!! I was feeling rather proud of myself so i decided to post here to see if anyone else had seem fluxos with that rubber gasket set up before and if they had issues as well. I now have 5 useable cartos when i had for sure thought i wasted my $$$. Ok sorry to ramble...im still a vaping newb and was very excited. 
Here is the little rubber gasket thing im talking about.
