Does anyone else have a problem with a burnt taste/extreme throatiness from their Protank 2? I love my original PT after putting an airflow control on it, but after a few seconds, my Pt2 tastes burnt. I changed the coil and it didn't help. I even left the coils on the bases and swapped them and the PT1 was great, but the 2 tasted burnt. I think it might be the bridge that holds the center tube blocking juice flow, but idk. I'm vaping 50/50 juice so I don't think thick juice is the problem. Any ideas?
