Using a three piece ecig, and can't figure out what I'm doing wrong with blue foam. Pulled out the existing batting from the cart, replaced it with the foam following all of the video instructions, and either 20 drops of juice go in and never come back out, or 20 drops of juice go in and come right back out all at once. so I either get flooded attys, or burned out attys, but no vape. HELP!!!!!
