1: Yuppers, using the cart that came w/ it. There is some sizzle.Are you using the carto that came with it? (smok 2.0 ohm dual-coil, I believe)
First of all, are you hearing the "sizzle" sound? Just to be sure you've got plenty of power.
Secondly, sometimes the cartomizers take a bit of a "break-in" period, and will get better.
What type of juice, i.e. PG/VG ratio?
Thicker juices (like 100% VG) take longer to soak in & get to the coil.
Lastly, it's possible that your carto is just a "dud" (it happens)
2: I'll try it some more tonight
3: Im using some Jameson's. Not sure of the ratio.
