A lot of factors can play in to this. A) faulty battery B) faulty charger C) faulty springs inside the mod D) bad connection between the battery and atty E) bad coil wrapping/something blocking the connection between the wire and the posts F) burnt cotton G) too high/low resistance My recommendation is all together to stay away from mechanical mods. You can get regulated mods that fire at whatever wattage you wish, so realistically you're only endangering yourself by getting a mechanical mod, there's no need for it. Also, spend the money and get some nice Sony 18650's and a smart battery charger that tells you the voltage and stops charging when fully charged. With what you have, it's really iffy. I'd be very wary, and personally if all you're getting is dry hits I wouldn't even use it. If you don't want to deal with all the battery nonsense, do what I did, get an istick 50w. When I bought it, it was like $50. Now, probably 5 months later, it's the only mod I use. And I'm sure there's other mods with built in batteries that go higher, I just haven't looked because I'm so satisfied with the istick. Have a nice little RDA on it vaping at a safe .3 ohms. There's really no need to go crazy and blow your hand/face off. At that point of cloud chasing (going below .3 ohms), you're just asking for trouble.
