I'm having a problem with the Kangar MT3 I received yesterday...I always am getting a mouth full of nasty juice and some gurgling, but a lil vapor for the first few hits then none, except for more liquid in the mouth...I made sure not to overfill and not to get juice into the center hole by using a needle pin tip on my bottle....so then I took out all the juice and base coil and cleaned it with a Q tip and rinsed out the MT3, let it dry, and then refilled it half ways (1-1.5ml) and still have the continous mouthful of juice with every hit..also I notice my 650a ego T battery connection gets very warm and the MT3 base/head gets very warm as well after a few hits, and the vapor is then non existent...at that point I change to a disposeable (2-4 week) top fill clearomizer from a local shop and all works well then and the battery cools down and I get no gurling and lots of vapor and a good hit the rest of the day...but if I wait a few hours and go back to the MT3, I have the same problem again with continous mouthfuls of nasty juice and a very warm base/head and battery connection, after 2-3 hits, and no vapor...I really don't know what to do at this point..
