Tokerpipes, in my experience with Pestersons, I have owned quite a few, that with the Systems, if you tilt the thing, the reservoir can spill over into the smoke hole causing the gurgling. Also, the humidity of the tobacco can also affect the gurgling. I would suggest trying to air out the tobacco you have been using, perhaps leaving it out overnight on a paper towel and see if that helps?What kind or blend of tobacco are you using if I may ask?
