Metering Rods - .070 x .047

The Edelbrock Metering Rods - .070 x .047 are precision calibration components designed for carburetors requiring exact air-fuel mixture control. As an experienced mechanic, you know that carburetor tuning demands accurate metering rods to achieve optimal drivability, fuel economy, and emissions compliance across varying load and throttle conditions. This pair of brass rods serves as the foundation of fuel delivery calibration on Edelbrock carburetors, making them essential for restoration work, performance tuning, and OEM-specification replacement.

Metering rods function by varying the fuel jet opening as the throttle transitions through cruise, part-throttle, and wide-open throttle positions. The .070 inch diameter and .047 inch step dimensions on these Edelbrock rods are engineered to produce a specific taper profile that meters fuel precisely during needle and seat transitions. Manufactured from brass for reliability and corrosion resistance, these rods maintain dimensional stability across temperature fluctuations and extended carburetor operation. The tapered design allows the rod to progressively uncover the fuel jet, preventing rich-running conditions during cruise while ensuring sufficient fuel delivery under acceleration and load.

Edelbrock carburetor owners and rebuilders benefit most from these metering rods when restoring original carburetors or troubleshooting lean-surge and hesitation complaints. Installation requires carburetor removal and disassembly; the rods insert into the float bowl and connect to the metering arm linkage. Verify your carburetor model number against Edelbrock documentation to confirm compatibility, as metering rod dimensions vary by jet size and carburetor design. Whether you're performing a complete rebuild or fine-tuning an existing setup, this pair ensures repeatable, factory-correct calibration.
