Having the same problem with mine. Coil burns pretty much evenly until its in the tank.
Then when the wick is soaked in juice in the tank there is a single hotspot from the coil leading to the positive post. But i guess thats normal right? Its not on the wick hence the kanthal wire gets hot? And i get that weird metallic taste with the flavour. Should i let it burn in more and see if its still there?
First time it happened i threw the wick away. Rolled a new mesh made sure this one was oxidized (did the whole process about 7-8 times - find it hard to believe its still not oxidized properly), and then coiled it (i did flame the coil too) and put it on did clone. Still getting the same problem now.
By the way, is that taste just something you won't like or is it actually dangerous? (vaping metallic fumes?

).
On a side note my first attempt brought about a 1.6ohms set up. The second is 1.0 ohms
