    Holley 2818 metering block gaskets

    The carburetor is a service replacement List 2818-1 on a 1965 L79 car. As shown in my photo, the K&B rebuild kit included one metering block gasket with a large U-shaped hole, and one without. Both of the gaskets (primary and secondary) that I removed from the carburetor had the large U-shaped hole, and appear to be identical to each other ... can I assume that this is this correct?

    The new gasket without the U-shaped hole does not fit the alignment pins for either primary or secondary metering block, so I assume it is the wrong gasket. When I contacted the vendor that sold the rebuild kit, they were very helpful and agreed to send out another gasket with the U-shaped hole. However, the vendor opened the box to another rebuild kit, and it too had one gasket with the U-shaped hole, and one without. Is this a coincidence that two different rebuild kits have the wrong gasket, or am I mistaken that both gaskets (primary and secondary metering blocks) are the same, and should have the U-shaped opening?



    Thanks

      Get a genuine Holley rebuild kit and make sure you match new gaskets to old gaskets to where they go and configuration.

        Who ever is assembling the kits is placing a secondary gasket for a 4160 Holley instead of a 4150 Holley which is what you have.

        Looking at that gasket again it may work fine but you better compare the holes to the metering block. The 2818 does not have a power valve on the secondary side.

          Thanks for the responses. Will check with Holley. And thanks for confirming that kit appears to be packaged wrong.

            Daniel, You might also buy the book if you don't have it, on rebuilding Holley carburetors that CC sells. It is a Workbench Series SA330. It is very detailed with great photos.
