Take all of the seals out. Anything hard and thin will do the job, maybe a blunt nail file or toothpick. Where you can see the two slots on the cup, that's where you want to raise it from. The one that sits over the cup, you want to cut the seal slots into a /\ shape. Just a bit wider and taller than they already are then stick the seal back on and you're ready to rock. Just tilt it upside down for a second or two to get juice on the wick when it's getting dry.
You can also just pull the seal slots up a little instead of cutting them. It's a little difficult to take the cup seal up the first time but after that it's a lot easier.
If you prefer, you can put the cup seal back in upside down so it will be a very fast wicking or put the middle circle seal (doughnut) on without the cup seal. This way you don't need a syringe to fill your CE2s as you can just slide the seal out and fill it down the sides. It will wick rediculously fast if you do it this way though.
Good luck!
