I have two of these cartos...
Black 801 Cartomizer
Bought them to use on a SparkPlug but there is zero airflow. Zero. Tried adjusting the internal screw but no luck. At $1.49 I should just toss them into the trash but I hate to waste anything. Plus I am curious to try an 801.
What is the absolute cheapest battery I could buy to use this carto?
