To clean the carburetor on a 4.5 hp Briggs & Stratton mower, start by disconnecting the spark plug wire for safety. Remove the carburetor from the engine, then take it apart and soak the parts in a carburetor cleaner solution. Use a soft brush to clean any stubborn deposits, paying special attention to the jets and passages. After thoroughly rinsing and drying the components, reassemble the carburetor, reinstall it, and reconnect the spark plug wire before starting the mower.
