I have only been baling for 6 weeks or so and have a Mini Protank 2. I have had several problems with leaking, burnt taste and gurgling from my Mini. I tried flipping the coil seal around which seemed to help the wicking problem but was still getting the leaking. After messing around with it I decided to remove the seal around the coil (the one around the stem of the coil). It works great now!! No leaking or gurgling, no burnt taste from a dry wick!! My mini is working great now!! Not sure why that seal is even on there because it doesn't seem to need it at all!!
