Im using the above, all was fine until I replaced the coil and now it's spitting hot liquid, tried a couple of different batteries with the same result
With all coils you get good ones and you get bad ones. It does sound like it is flooding and there is not a lot you can do about it unfortunately. Get yourself some more and see if they are any different.
It happens sometimes when I make my own coils, it looks exactly the same as the old one but as everything is hand made and not done by a machine things can vary.
Could be a bad one yeah i guess, love my nautilus it's fantastic and actually never had a bad coil myself yet and must have used about 25 by now.
Stick a new one in dont over tighten, i always add drop or two of juice into the coil and leave mine to soak for 10 mins before puffing.
