Hi I need help, I have a Kagertech tank with an rba that when I bought the setup the guy who sold it to me made the setup and it worked great, now I tried to wick my own coil and failed and the guy said I used too much cotton, he makes me a new wick and now I can't take more than 3 hits without getting this burnt rubber hit that burns me, how can I fix it? is it the coil? Is it the cotton?
