I got an aging one here,try this:
Lift up the coil cap high enough so when you insert the mouth piece back,they touch each other;
Then vape with the tip of your PV upward...I find that you can chain vape that way with no gurgling or burnt taste...at all.
If you tip it down it will gurgle,but tip it up again and a couple vape will stop the gurgling and its chimney action again.
At least this work on mine with alien vision banana stuff.
