Part Number:S101
The metering rods are of a step design and are controlled by vacuum and metering rod spring action. At low speeds the metering rod is dropped down into the primary main jets, thus partially closing off the flow of
fuel. At higher speeds and less vacuum the rods pull up from the main jets allowing more fuel to flow. Experiment with different springs in order to remove any flat spots, especially if the engine is running any kind of performance camshaft.

Also fits Carter AVS carbs.

Carter AFB, 4 barrel metering rod springs. Includes 10 springs, two springs for each color. See #17 in the illustration.

The springs are of good quality. However, it would be more convenient if a copy of the spring pressure chart came with the springs.

I've worked with the springs one time only and changed from the lightest to what I thought was the next tension. I got results that were expected except for one problem. I have two carbs and the second set of springs that were shipped did not have a good color match and were short on the count. I matched by the diameter and length to get the second carb set up and being that my engine is still breaking in, I'll have some more experimenting to do in the future after break in.
