Metering Jets .077

The Edelbrock Metering Jets .077 (Part No. 1420) is a precision carburetor component designed for tuning and optimizing fuel delivery in performance and stock carburetors. These metering jets are essential for carb enthusiasts, engine builders, and mechanics who need to dial in air-fuel ratios for peak engine performance across varying load conditions and altitudes.

The .077 orifice size of this metering jet controls the amount of fuel delivered to the main circuit during cruise and part-throttle operation. Edelbrock's precision-engineered jets maintain tight tolerances to ensure consistent fuel atomization and combustion, reducing hesitation, stumbling, and rich or lean running conditions. The small, lightweight design allows for quick swaps during dyno tuning or field testing without breaking down the entire carburetor.

By selecting the correct jet size, you can compensate for fuel pressure variations, air density changes, engine displacement, or intake manifold design—making metering jets one of the most cost-effective tuning tools in any mechanic's arsenal. This metering jet works best for owners of carbureted vehicles running Edelbrock carburetors or compatible aftermarket units where fuel circuit tuning is required.
