Adjusting the high and low mixture screws on a carburetor is a critical step in tuning an engine for optimal performance and fuel economy. The high mixture screw controls the fuel-to-air ratio at high throttle openings, while the low mixture screw controls the fuel-to-air ratio at low throttle openings.

When the high mixture screw is set too lean, the engine will run hot and may experience detonation. When the high mixture screw is set too rich, the engine will run rough and may produce black smoke. The low mixture screw, when set too lean, will cause the engine to idle roughly and may cause stalling. When the low mixture screw is set too rich, the engine will idle smoothly but may use excessive fuel.
