Shielding sensitive components: In the demanding world of kart racing, the Diaphragm Cover (SKU 555112) for Briggs Raptor engines—superseded by 691713—plays a pivotal role in safeguarding the carburetor's diaphragm.

This leads to more predictable handling and the confidence to push limits without fear of stalling.
