Air Vane Spring and Governor Spring for B-Riggs & Stratton Engines: Fix Choke on Lawnmower

Replacement part number 699056 is compatible with Briggs & Stratton models 122H02 and 122K02, with a corresponding part number of 490-404. On the other hand, replacement part number 790849 is the spring that connects to the choke arm above the carburetor.

The 699056 spring is designed for easy installation on Briggs & Stratton engines. Specifically, it functions to close the throttle plate when the engine is cold. This part is essential for repairing the auto choke system on Troy-bilt, Craftsman, Toro Recycler, and Brute lawnmowers that are equipped with a BS series motor.

Engines that do not have a choke will not start without the air vane spring. The air vane itself serves as a replacement for a traditional choke, and the spring plays a crucial role in this mechanism. This part is particularly useful for replacing a missing air vane spring on a lawnmower with a Briggs & Stratton engine.

The 699056 governor spring is responsible for applying tension to the throttle in order to regulate the engine speed effectively. On the other hand, the 790849 air vane spring is a crucial component of the auto-choke system, ensuring that the air vane maintains the correct amount of tension for optimal operation.
