Ok so I quit smoking analogs about 4-5 weeks ago and bought myself a Joye 510 kit. After I realized I had a completely new addiction called vaping I went on and ordered from totally wicked a 3.7V Screwdriver MK2 and a 3.7V Tornado. I have the stock attys and for the first couple days I didn't touch my 510. Now I don't know if it is user error which I believe it is or a problem with both units. I started the drip method and really enjoyed it but when at work I am unable to keep dripping. I normally have to use carts. So with all this said both my screwdriver and my tornado have been giving me problems. I can top everything off and when I go to cape on either one I have to do about 5-6 initial pulls to start getting vaper. I cannot get a good strong blast of vaper if I try. I have tried different juices and none have worked. I am currently using nuvape's high voltage cherry bomb juice. Awesome by the way!!! Does anyone have ideas or cures. I have also cleaned out all of my attys too.
