What is the purpose of metering rods in a carburetor?

Metering rods work with the carburetor's main jets to control the flow of fuel into the engine. As the throttle opens, the rods move, changing the effective size of the fuel passage and thus adjusting the air-fuel mixture based on engine demand.

Can these metering rods be used on any Edelbrock carburetor?

No, these specific metering rods are designed exclusively for Edelbrock Thunder Series AVS Carburetors. Using them on other carburetor models may not fit or function correctly.

What does the .070 x .052 sizing refer to?

The .070 x .052 sizing refers to the diameter of the metering rod at its two key points. This specific size is chosen by Edelbrock to provide a particular fuel flow characteristic for the Thunder Series AVS carburetor.

Product Details

These are Edelbrock Metering Rods, specifically the .070 x .052 inch pair, designed for use with Edelbrock Thunder Series AVS Carburetors only. Metering rods play a key role in calibrating your carburetor's fuel delivery, affecting how much fuel gets into the engine at different throttle positions. If you're looking to fine-tune your carburetor's performance or are in the middle of a rebuild, these rods are a direct replacement part.

This particular set features a .070 inch diameter at one end and .052 inch at the other, offering a specific calibration point for your Thunder Series AVS carburetor.
