Don't know -- could be the bowl vent valve if the hard starting is only with a warm/hot engine. Mine went that way, first just hard to start then almost impossible. Also lacked power and had the absolutely WORST gas mileage you can imagine.

If you do a search on here under bowl vent valve you should find lots of good info, or post back and (when I'm not at work) I'll tell you how to check it.
