Just started and got thru my first charge in the cart. Using a liquid I ordered with my kit, 14mg strength. The only flavor I'm getting is a plastic taste possibly from the plastic tip. Is this normal?
Try cleaning it out, drying it, and see what happens from there.
Make sure that your cart is seated correctly in the atomizer. The two flat sides should be parallel to the bridge of the atomizer. When I used carts, I switched to the whistle tips so that took all the guess work of aligning it right.
Carts can be very annoying that way. Hard to keep them working well. It sounds like the cart is getting dry. Make sure you are topping the cart off often and not trying to get all the juice out before refilling. You can even place a drop on your atomizer when refilling. If you vape frequently, carts can not transfer as much juice to the atomizer as the atomizer is using.... Look into direct dripping. I've tried many many mods to carts to get them to perform to my liking. Sometimes they work well, sometimes not. Carts seem to me the most work in the whole vaping experience.
Like I said above, get a drip tip and direct drip your juice right onto your atomizer A drip tip replaces the cart. There is no polyfill. Just a hole in the mouth piece for you to drip your e juice directly onto your atomizer. Most recommend 3 drops per filling. The drip tip will last forever almost. The vaping experience is better and you finally eliminate the hassle of carts.
You could also try using a cartomizer instead of atomizer/carts. Cartomizers will not last nearly as long as a good atomizer, but they are cheap.
Madvapes and many other suppliers sell drip tips. 901/510 tips are the same size.
This is exactly how I ended up doing it. I then ordered a drip tip but found that during a drag, I get a little bit of liquid on the inside of my bottom lip and it would actually create a burn. I just stopped the drip tip and went back to using my empty carto, which I made even shorter by cutting it down a bit. ( the end that goes into the atty)While you are waiting, you can make your own drip tip of sorts. Just take the polyfill out of one of your carts. Or use a cart that came on the atty- same thing. If your atomizer is dry, just place a few drops right onto your atty and pop your empty cart back on. It will vape similar to a drip tip, you'll just have to pop it off you atty to refill instead.
