Ok I already posted that I'm trying to convert over to carto/tanks. I have 3 IB tanks. 2 19mm and one 25 mm. Today the 19mm both of em started popping when I take the first vape from em then they settle down. The 25mm never has done this. I've tried doing the dry hits to make sure it's filled but truth is it sounds like a flooded atty does when I drip to much. (which is almost always). Another one of those "tnt56 don't understand moments". Thank God for ECF.
