Metering rods work in conjunction with the metering jets to control fuel delivery at different throttle positions. The stepped design features a thicker upper section and thinner lower section—as the rods lift with increased engine vacuum, more fuel flows past the thinner portion, enriching the mixture under acceleration. Selecting the correct metering rod diameter is essential for achieving the proper air/fuel ratio for your specific application.
