Edelbrock 1446 Performer Series Carburetor Metering Rods .068 x .042 Inch Pair

The Edelbrock 1446 metering rods are precision-engineered replacement components designed for Edelbrock Performer Series and Thunder Series AVS carburetors. These metering rods play a critical role in controlling fuel flow through the carburetor's main metering system, directly affecting air-fuel ratio and engine performance across different throttle positions.

Key Specifications:

• Primary diameter: .068 inches
• Secondary diameter: .042 inches
• Sold as a matched pair (quantity 2)
• Direct replacement for Edelbrock Performer and Thunder AVS carburetors
• Precision-machined for consistent fuel metering

Metering rods work in conjunction with metering jets to regulate fuel delivery based on engine vacuum and throttle position. The dual-diameter design allows for leaner mixtures at cruise (larger .068" diameter restricts flow) and richer mixtures under acceleration when the rods lift (smaller .042" diameter allows more flow). Changing metering rod sizes is one of the primary tuning methods for Edelbrock carburetors, allowing you to fine-tune performance for your specific engine combination and driving conditions.

These rods are essential tuning components for optimizing throttle response, fuel economy, and overall engine performance. Always replace metering rods as a matched pair to ensure consistent fuel delivery to both primary venturis.
