Hello and welcome to the forum. Glad to have you here!
If you are getting a burnt taste (we call those "dry hits"), if usually means your wick cannot pull the eliquid fast enough to keep up with your battery. There are a couple of things you can do:
1. Dial down your voltage. This will vaporize the eliquid at a slower rate (if your battery allows you to do this)
2. Decrease the airflow, if your tank has adjustable airflow. The decrease in airflow will increase vacuum inside the tank's atomizer, which should increase the flow of juice to the wick..
3. Take a sharp draw (or two) on your drip tip (without engaging your battery). This will pull more eliquid into the coil so that it will be available when you press the battery button and take a draw.
You will get the feel of this over time and develop a sense of how often you will need to do this to avoid "dry hits". The PG/VG ratio of your eliquid also comes into play, as VG is thicker than PG . If you use high VG try adding a few drops of distilled water to your tank to thin out the eliquid. You could also install a higher ohm coil.
