Primer bulb not working

I have a pusher mower with Briggs & Stratton engine. I have just replaced the primer bulb and now it doesn't squirt any gas when I press it. I can hear the air going in and out and I suspect a check valve (if there is one) isn't working. I don't know the part # of the mower but it is from 2007. I think the carb part number is 494406.
