hi Shannon being a rover 45 it should have a briggs Stratton engine
some times the diaphragm in the carb gets old and tired and if you ran it dry of fuel it can have trouble drawing fuel up from the tank up into the carb and motor just by pulling on the cord.
you could try filling the tank to the brim and give that a go, making sure throttle and carb are on full choke for cold start.
and as norm said check for spark.
good luck damo
