Correction: I used two strands (2/3 of a millimeter) for the flavor wick and two mm for the coil wick. for some reason it works better on the EVOD
Here is a quick fix that woeked on all my PTK and Evods :
Leave the coil alone.
1. Remove the Flavor wick
2. Wash the coil
3. Assemble the coil on the base and give it a few pulses for it to clear the gunk (smoke)
4. Take a 2mm silica wick, open the strands - there should be 6 strands. use 3 strands
5. Place 2-3 strands (less than equivalent) where the flavor which was
the above works Fine even if the coil is all gunky as long as the wick in the coil is not burned out. it takes 5 minutes.
