Function & Purpose
Air corrector jets work in conjunction with emulsion tubes to control the air-to-fuel mixture throughout the rpm range. They provide precise air metering that affects the fuel mixture characteristics, particularly in the mid to high rpm ranges. Proper sizing is critical for optimal engine performance, fuel economy, and emissions control.
Quality Assurance
Each jet is manufactured to original Weber specifications with precise bore dimensions and smooth internal surfaces. The brass construction provides excellent durability and resistance to fuel-related corrosion while maintaining dimensional stability over time.
Installation Notes
For twin-barrel carburetors equipped with two emulsion tubes, typically two identical air correctors are required. Professional carburetor tuning knowledge is recommended for optimal jet selection and installation.
