Weber DCO DCOE Air Corrector Jet

Air corrector jet for Weber DCO/DCOE

Original Weber air corrector jet for the main circuit of DCO and DCOE carburettors. Controls the air bleed into the emulsion tube and is used to tune the mixture at higher engine speeds.

• Original Weber component with consistent machining tolerances
• Sizes 100–240 in steps of 5
• Fits Weber DCO and DCOE, including common 40, 45 and 48 applications
• Works together with the main jet and emulsion tube

Technical specifications

• Larger air corrector: generally leaner at high rpm
• Smaller air corrector: generally richer at high rpm
• Circuit: Main-system air correction
• Suitable for systematic rolling-road or track tuning

Installation and use

• Set float level and fuel pressure before tuning.
• Adjust in small steps and evaluate the engine under load rather than free-revving.
• Check the emulsion tube if a transition problem cannot be solved without compromising another range.
