If you are using high VG juice, you may need to remove a flavor wick, so more juice flows into your coil. You didn't say you were using a vv Evod, so I'm assuming you are using a constant output Evod battery, so unless the battery is faulty (possible), too much power is not your problem. If it is a vv battery, turn it down to the lowest setting & start working the power up until you find the level you like, without it tasting burned.
The Protank2 takes a single coil head. Make sure that is what you were sold. They are a bit smaller than the Kanger dual coil heads. Look at the silicone piece that sits above the coil, & around the stem. If it is aprox. 2mm (1/16"), it is the correct one. If the silicone piece is 4mm (1/8") then you have the wrong coil. Also, if there are no wick showing and the silicone is just a flat washer-type piece, then it is a newer dual coil - and also the wrong one. If you take a pull on your tank (without firing the battery) are you getting a good draw or is the airflow tight? It is possible that (if you have the right coils) your coil or tank is tightened down too far & limiting the airflow. If it's a regular size PT, check to make sure the airholes in the 510 base are clean & not clogged, also check the battery neck & make sure it is not blocking airflow. If you're using a PT2 mini, check the air hole in the base. It can even be drilled or filed a bit to increase the airflow.
Have you had this problem before or has something changed? New adapter? beauty ring? Let us know how things are going & if any of these things help. Good luck.
