This is a complete Holley List #76750RD Ultra Double Pumper. There is no broken, frozen, or missing parts. Will need a cleanup and new gaskets, which is why it's listed as For parts and not working. Carb looks clean outside, but should never the less be taken apart and checked as we have not run this carb ourselves. This model Holley was a 750CFM Double pump carb that featured many upgrades over the standard 750DP carb. Has 6061 T6 Billet Aluminum Baseplate and metering blocks which have been Red Anodized. The rest is cast aluminum with shiny zinc finish. Carb is very clean and all shafts move easily. All electric choke parts are intact. Has clear sight glass in the bowls for float adjustment. Metering blocks have four corner idle screws. These are VERY EXPENSIVE new at over $900. Buy this one & rebuild it for half of that.
