Hi people, im new here, new at vaping, and new at english, but i hope you will understand me 
I bought two Kangertech AeroTanks (510)
One of them works perfectly, but another one after about two weeks of using got one problem:
Air not incoming easy. Very small air amount comming into tank with fully opened holes and removed coil.
So im sure that problem is with airflow base. Im checked all holes with a needle and found that all holes is free to air.
Cleaned with hot water everything but still air going with very small amount, heads have to much vacum, gurgling and almost no fog producing.
Have abyone any tips from own experience?
Sorry for my terrible english and hallo for all vapers from another new one
