Spitting may ease up as your coil breaks in, but you really want to make sure your coil isn't flooded. It can sometimes take a few blows out of the airholes to really achieve that. Also check all your connections for tightness, to make sure nothing has come loose. A longer driptip can sometimes help with spitback, depending on the magnitude.
For me, with some setups, a particular coil (be it RTA or drop-in) just wants to "spit". Solutions I have found useful: turning airflow up/down, turning wattage up/down, replacing the coil with a different build if it's an RTA (sometimes if I have a lower resistance coil than usual and want to vape it at lower watts, it's not going to cooperate), turning to Temperature control mode (if possible depending on coil material) waiting for the break-in period to pass (I had a Fusion kit that flooded on my like crazy the first time I primed it, thought it was going to be unvapable but got it sorted out and now I LOVE the vape). This was on a fixed wattage (30 watt, high for me) 0.8 coil that turned into a very airy vape that I actually love, but it sure took some breaking in. I rotated drip tips until I found something workable, but yeah, I was pretty much sucking on e-liquid for a while. It wasn't pleasant, but it did pass, especially when I started playing around with driptips.
I find ultem drip tips to be the best for cooling down a "warm" vape, which I almost never experience but with that Fusion kit it was just the ticket.
Best of luck,
