I haven't had much time to do any smoking. And I have slept since my last smoke. (that's my excuse i use for being forgetful) So I'm asking a basic question. When I smoke with my air intake closed (I don't have a damper on my smoke stack), I get heat, but not much smoke. Should I open my air intake to allow more air in which will keep the volume cooler but allow the heating element to get hotter which in turn makes more smoke? Any rule of thumb? Thanks
