I fell off the wagon and started smoking....booo hisssss, I know. But I am back to my senses now and I need expert help to stay on track. My Tornado, isnt up to par. Its been sitting, ignored and lonely for 10 months and now its has these issues: weak vapor at start up and lasts like 5mins. I am using brand new batteries charged and ready and brand new 510 attys. I hate carts so I drip. It seems like it needs a tune up?? Im positive it worked great the last time it was used but now its just crap. Please help. I have cleaned the contact points and threads on the body of the mod itself and Im wondering if the adjustment screw on the side may need "tweaking"?
