Ran out of gas, filled back up and wont start

Try removing the airbox on the side. Cup your hand over the inatke while cranking the motor. Do that for a couple of motor rotations. Once you've done that try restarting it without cupping the intake. Sometimes it takes a little extra suction to charge the engine with fuel or the carb isn't able to draw enough of an initial charge to start it. If that doesn't work hold your finger over the exhaust tip while cranking and release it while still ccranking it over. A couple of times doing that and she should fire up. If that doesn't work then I would check to make sure you are even getting gas to the float of the carb at all.
