Venturi nozzle for Weber 45 DCOE carburettor - 28 mm

This 28 mm venturi nozzle is designed to equip the Weber 45 DCOE carburettor, a dual-body carburettor with horizontal inlets widely used on classic sports vehicles. It plays a central role in forming the air-fuel mixture by ensuring acceleration of air flow at the mixing chamber level. Its replacement is recommended during restoration or overhaul of a carburettor showing wear or degraded performance. A nozzle in good condition contributes directly to idle smoothness and throttle response.
