ive got a problem with my evo, its a v2 or v2.1 and most of my cartos do not work. it just blinks white 3 times... im not over tightening them at all, in fact, im using a smoktech carto tank so i cant over tighten. the o-rings are loose so the tank just spins around the carto. but no matter what i do i get the 3 white lights. yesterday i got the switch replaced and a couple hours later i got the same issue... anyone know whats going on? i can still use a carto if i loosen it with about a 1/4 - 1/2 turn but by then its too loose and will rattle. it seems like i do have one older carto that still works on it, but that is out of 10-15 cartos! even open up a new box and none of the 5 worked.
help please
