Designed for use with the Edelbrock Performer and Thunder Series carburetors only. Rods are incredibly easy to change. Metering rod is used to control the air/fuel mixture. Diameter of the cruise and the power is 0. 070 and 0. 042. Allows you to fine-tune your carburetor for optimum performance.
These dipsticks have worked well for my AVS2 carburetor. At over 4000ft the bars are too thick so I followed the size chart and these bars fit my height. The state is no longer rich.
