I have a tesla mod with a kanger pro tank 2 after a few days my juice started to taste burnt. I followed some guides on youtube about cleaning the coil taking it apart cleaning the flavor wicks and dry burning. I put everything back together and i started getting juice in my mouth. I thought i may have messed up the flavor wick so i replaced it with peaches and creme cotton yarn. Now when i try to draw its really hard and get almost no vapor.
