The Edelbrock jet and rod kit for #1825 and #1826 AVS Thunder carburetors supplies the small metering components required for proper calibration. Intended for those AVS models, the kit helps tune fuel delivery and restore correct jetting during a rebuild or setup. It also references the Thunder AVS family’s adjustable features, including Edelbrock’s Qwik-Tune adjustable secondary air valve on related parts.
