well im starting to wonder if some models are designed more for filling the cart vs some designed for dripping. like my janty mini fogger aka joye 306. it seems to never work well if i fill the cart, it just produces a burnt metal flavor, im always dripping with it. then i have my 510, and since the atty isnt exposed, it seems to work better by filling the cart. am i just doing something wrong, or is this common?
