I have a 2004 Broodmoor 16HP Briggs&Stratton Vanguard Twin and the engine blew a rod over the weekend. I am trying to find the replacement engine but can't seem to match up this model number anywhere. (303777-1114-E1) Does anyone know if there is a new cross reference so as I can purchase a new engine or a part number for a new engine. Thanks in advance.
