Description
The Briggs & Stratton 555594 Pilot Jet is a crucial carburetor component for Animal and LO206 engines. Its primary function is to regulate the fuel flow at low throttle (idle and part-throttle conditions) by controlling the amount of fuel that mixes with air before entering the engine. This ensures smooth idling, improved throttle response, and consistent fuel delivery at lower RPMs, which is essential for maintaining stable engine performance in racing applications.
