The tank and bowl fill after a flush, but during the flush the tank empties and water in the bowl slowly swirls and fills up the bowl more than it drains.

If I take a bucket of water and dump it directly in the bowl, it flushes and the bowl empties. So no clogs there. I've also replaced the wax ring and inspected the drain w/out the toilet. No problems there when I dump a steady stream of water into the drain.

Any ideas on what else I can look for? Maybe it's time for a new toilet?

Thanks!

Ok, got it fixed. A few of the holes in the rim were clogged w/ build up from minerals... I cleared them out w/ a paper clip and all is well now!

Thanks to speedball1's advice from another post, it helped a lot.
