BRIGGS & STRATTON 690023 Engine Choke Shaft

The Briggs & Stratton 690023 Engine Choke Shaft is a part used in small systems carburetor assemblies to control the plate position during starting and warm-up phases. It operates by transmitting rotational movement from the choke control lever to the choke plate inside the carburetor, adjusting airflow to the fuel mixture. This mechanism assists to regulate air restriction when starting a cold engine and gradually returns to normal airflow as the engine reaches operating temperature. It is mounted within the housing where accurate alignment supports smooth throttle and choke coordination during engine operation cycles.
