It works in conjunction with the emulsion tube and air correction jet to provide proper fuel delivery across the engine's operating range. The main jet determines the base fuel flow rate, with the air correction jet providing high-RPM fuel mixture control.
Installation Main jets push into the emulsion tubes within the carburettor body. Professional tuning is recommended to select the correct jet size for your specific engine configuration and performance requirements.
