I haven't tried an evod but if you are getting a burnt taste it usually means that the wicks/wicking material is dry or has not soaked up enough liquid. Whenever I change out the coils in my clearo I usually let it sit a few minutes before using it so that it can soak up liquid. Then, I usually take a few draws on my ecig without hitting the battery button just to draw in liquid. I also usually take shorter draws on it at first to make sure I don't run the wick dry before it is totally saturated. If the coil head on your evod has little wicks sticking out you could even put a drop on the wicks, put the evod back together, then try again. Hope this helps and that you get it going. Maybe someone who uses evods will help out more. Good luck.
