Poor running at wot, but idles good, can be an air leak. Possible your lines are sucking in air some where or a bad fuel pump.
Quick way to troubleshoot this is to manually pump the primer bulb at wot, if the wotor runs good then it is possible there is an air leak or bad fuel pump.
Your fuel filter should stay full.
