It's not exactly like gurgling it's like someone drip a drop under the coil but when i do dl the problem decreases for a while. I forgot to tell...a friend gave me the precisio and I have the exact same problem, wicking?
After so many tries I can't wick correct either the prime or my new favorite lite, I'm using 50/50 juice, I don't have any leaks or bad flavors, but after a day of new wick my airflow becomes more tight and o something like gurgling, this is an old build.
