I found that the prefilled carts make for a cruddy TH in my opinion. Take that pre-packed stuffing out and replace it with some poly-fill (polypropelyne pillow stuffing -available at wal-mart in the crafts section ~3.00 for a bag that will last you a lifetime) pack it in your cart very lightly.This will help drain. Youtube has some videos from nice peeps available as well to teach you. This is how I learned. I find it works best, but different people have luck with different things. Check the modders section out and do some research. It may also have to do with your juice strength also. Pre-packaged juice never seems strong enough to me. Get some good 24mg strength juice. If it's too strong, just hit lighter, but this probably won't be the case. I've also found that the 3 different kinds of menthol I've tried in the highest strength possible sooths my hit and I keep trying to chase my tail on the TH. Hope this helps! GOOD LUCK!
