Metering Rods - .065 x .052

The Edelbrock Metering Rods – .065 x .052 are precision brass fuel metering components designed for anglers and boaters who rely on carbureted marine engines to stay on the water. These rods are essential tuning elements that regulate the air-fuel mixture ratio at different engine speeds, ensuring your boat's carburetor delivers optimal performance across throttle ranges. Whether you're running a classic inboard, outboard, or auxiliary engine, proper metering rod selection directly impacts fuel economy, engine response, and overall reliability during long days on the lake or ocean.

Constructed from durable brass with precise outer diameters of 0.065 inches and 0.052 inches, these metering rods work in tandem with the carburetor's main and secondary jets to control fuel flow as engine load changes. The tapered design allows the rod to move within the jet opening, restricting fuel passage at lower throttle positions and opening it fully at wide-open throttle. This mechanical precision ensures your marine carburetor maintains the correct fuel-air mixture ratio across the operating band, preventing lean-running conditions that can damage pistons or cause hesitation, and avoiding rich mixtures that waste fuel and foul spark plugs during idle or light cruising.

Boaters maintaining Edelbrock carburetors on single or twin-engine setups will find these metering rods essential for carburetor rebuild kits and performance tuning. The pair configuration (two rods per package) suits dual-feed carburetors common in marine applications. Installation requires careful removal of the carburetor bowl and float assembly, proper cleaning of bore surfaces, and precise repositioning into the metering circuit. If your engine shows sluggish acceleration, inconsistent idle speed, or poor fuel economy, worn or incorrect metering rods are a likely culprit—replacement restores carburetor function and engine performance to factory specification.
