"Eric and Megan Swope"

Try this experiment. Dump a bucket of water as you flush the toilet. If
it still doesn't flush well, then the problem is either in the bowl or the
venting or the soil pipe. If it does flush forcefully, then the problem is
in the tank or rim. Report you findings back to the plumbing newsgroup.

Of course, you can write the DIYers. They're always good for a few
laughs.
