Technical Information

Air corrector jets work in conjunction with the main fuel jets and emulsion tubes to provide proper air-fuel mixture throughout the RPM range. The air corrector primarily affects fuel metering from mid-range to high RPM, helping to lean out the mixture as engine speed increases.

Note: Most Weber carburettors equipped with dual emulsion tubes require two identical air corrector jets for proper operation.
