Maybe someone can help me here, I have tried so many different things. So when I screw my protank on my device -eVic, Zmax - MVP , it gets no draw. Its like sucking on a stopped up straw. I have spare bottom bases for the Protank so have tried drilling out the 3 holes on the bottom of one to see if it would help, no dice. Tried replacing the coils completely , no dice. If i unloosen the Protank it gets a draw , but it has to be so loose that the tank doesnt even make contact with the center pin. Anyone have any experience with this and know how to fix it?
