providing consistent fuel flow and optimal combustion efficiency

these small orifices can accumulate oil aerosol and moisture

allowing for granular field adjustments via the calibration spring

Efficient Cooling: Open Drip Proof design allows for maximum heat dissipation during high-demand cycles

The primary difference is physical size
