Your Vanguard engine part numbers can be found in your engine's Illustrated Parts Lists (IPL).
In order to download and view the correct Illustrated Parts List and determine the correct part numbers for your specific engine, you will need to Find the Model Number on your engine (Example: 12H702-0505-E1). Engines built before 1965 may use the model number and first 4 numbers of the serial number.
Once you identify the correct Part Number needed, you can order engine parts for replacement through Small Engine Warehouse Australia or your nearest Briggs & Stratton Dealer
