I'm just a bit disappointed. I sold a Mya Obelisk which smoked really well, and the KM just isn't living up to it's reputation. All the gaskets are good, everything is sealing properly. Plenty of air flow in the mod bowl ( I used it on my MZ and it smoked like a champ). I tried an egyptian cobra hose in place of the KM hose....still not much smoke. Very thin. I'm starting to wonder if there's a problem with the heart.
