Skystar Revvo Kit spitting and crackling

I need to know if my Skystar/Revvo kit is working correctly. After I let it rest for a while, I've learned the hard way that I have to fire it without taking a draw. The first time it fires after an hour or even just a few minutes, the liquid comes out like a very loud pop with it's own vape ring coming out the center. During draws after the initial pop, I'll fire it again and it crackles and spits juice... I have it currently running at 56 watts, any lower and all I get is juice in my mouth, any higher and the crackling gets louder. I'm currently using a 70 vg / 30 pg juice.

Please help! Any suggestions?
