I'm having trouble with the Ce3 Smokymizers lately. I can fill them without dripping juice everywhere but for some reason, juice collects at the top and I can't seem to figure out why. Ever 1/3 of a tank, there is a good 1mm layer of juice just pooled at the top. I have to take off the delrin cap and clean it out with tissue lest I get a splurt of juice. Can anyone help me? >.<;;
