This has worked for the cartomizer. Thank you and to those who also offered suggestions. Now I have to figure out the tank problem.
Well at least you have figured out that the Provari isn't the problem.
Don't feel bad tho' we all have our moments.
When I first got mine, all my tanks wanted to seal off the air flow. I was spitting nails I was so mad! Never occurred to me that maybe raising the tank up a bit on the carto might help.
