Can you try your 2.4 Ohm loads at higher voltage? Perhaps the cart isn't so contaminated as the oil tastes different because of the higher heat?

I will try that when my roommate gets back as he owns the only persei in the house. But here's another reason why I think it's the carts. I just tried to pre-oxidize another 1.5 cart while i have a loaded 1.5 cart I'm taking rips off of. The smell that lingers after the cart has been pre-oxidized is the same as what I taste in the loaded 1.5 cart. It is different because it is mixed with wax but u can tell its still the same taste when u have an empty cart to smell. Even draw a hit off the empty one u don't even have to press the button to taste it. Then taste the loaded one. There is definatly something wrong, Unless I magically got bad carts from thc and illusions glass Denver.
