Metering Rods - .065 x .047

The Metering Rods - .065 x .047 (MPN 1445) are precision fuel metering components designed for carburetor tuning and engine optimization. These rods are essential for automotive enthusiasts and professional mechanics who require precise control of the air-fuel mixture across various engine load conditions. They are particularly useful for those working on performance builds, classic car restorations, or street engine fine-tuning.

These metering rods function by regulating fuel flow through the main jet circuit as engine vacuum and load change. The tapered design allows for an increase in fuel delivery proportional to throttle opening, preventing over-rich conditions during cruising while ensuring adequate fuel supply during acceleration and wide-open throttle. The .065 diameter rod with .047 jet orifice dimensions provides a balanced taper profile suitable for a range of engines requiring moderate jet sizing.

Proper selection of metering rods is crucial to prevent lean-condition damage, reduce emissions, and optimize combustion efficiency across the RPM range. These rods are versatile and can be used in various carbureted applications, making them a valuable addition to any mechanic's toolkit. Their precision machining ensures consistent taper geometry, which is critical for smooth power delivery and predictable drivability.
