Holley includes several throttle plate gaskets in every Renew kit. They all fit specific carbs, and you'll need to be sure that each passage in your carb/throttle plate is correctly aligned in the gasket. Don't just rely on the throttle bore opening to determine the correct gasket. Pay close attention to the idle circuit holes the pencil is indicating here. Some double pumpers have these holes inline, but they are offset in others like this carb.
