similar lawn mower won't start at second attemp

mine (yard machine 675 series 190cc briggs and stratton) was sitting idle for probably five years. no gas no oil this morning.  opened up carberator and saw deposit inside. cleaned the best and put back, still won't start, it felt no fuel at the spark.  The spark plug looked prestine.   I shall check twice of the carberators.
