If I use a larger flame I can taste burnt air, this is why I keep my flame down on the small side and just tickle the flame through the tube, then pull the flame that bit further away when I see vapor, and back in again when the vapor fades.

I also like to inhale for longer than the instructions say too, 20 seconds or so to get a real lungful.

I discovered this using a little flame thing when my lighter gas started running low, and I was too smashed to face the public.
