When you get around to buying repair kits, be careful. There are four different bowl cover gaskets used on the YH Carters. Both of the 2 in the aftermarket kit available at the FLAPS are incorrect for the 2066s Corvette carbs. Also, fuel valves SHOULD be the spring-loaded variety. The solid type will run the engine in the shop, but will leak when driving.
Main jets are the same type as genuine Carter AFB, so the 10-201 Carter strip kit has a good selection of different size jets. Since you have 3 carbs, and there are only 2 primary jets in the AFB, you will require 1 1/2 kits (or buy individual jets).
