Hi, I'm having a similar problem. Plumber told me it's the jet. Can you give me ANY hints on how to open it up more? Lime away? What tools? He poked at it for a while with a pick. However, I don't see the water draining well yet.

I already opened the holes under the rim, and tank fills with water well. But the toilet doesn't empty.

Thanks for any help!!
