Poulan weedeater prime bulb won't compress

I just replaced the fuel lines on my poulan pro 31cc weedeater. It starts great but only runs for a little bit could have reversed the fuel lines? The bulb is hard as a rock and full of gas I also put cleaner in the carburetor. Please help

Are you gonna post this in every forum up the line (leaving Briana a mess), or are you going to post the damned thing in "General Discussion" or "Small Engine and Mower Repair" where it frickin BELONGS?????
