First, Tribecca by Halo is a good juice. Second being new I assume you got standard which is 70vg/30 pg.
Second that is a sun-ohm device - a cloud chaser machine. Okay they can be used mouth to lung (like smoking) but, you have to learn how to do it. Short (1 to 1.5 second) hits and very light pull. They produce a lot of warm vapor very quickly, not a bad thing but, that 1-1.5 seconds is going to get you about 1/3 more vapor than the volume of smoke in a pull form a cigarette.
It's spitting and gurgling because you are pulling on it as hard as you did cigarettes, that's pulling juice through that doesn't have time to vaporize.
Prime a new coil, with the cotton in it, put that in the device, wait 5 minutes for it to soak up juice, try vaping lightly for just a second. Adjust the length of time of your pull to suit you. ALWAYS pull very lightly, gently suck in air and, thus vapor. When your mouth is comfortably full, let go of the button and inhale if desire. (Don't have to inhale, nicotine is absorbed through the membranes in your mouth and nose too, so don't have to inhale to get nicotine.
