Marine Carbs

I live on the coast and have come across some smokin hot deals on marine carbs...but w/o vacuum, they're worthless to me.
Ditto. I bought an Edelbrock marine carb by mistake on ebay. Didn't notice was under listed in "boats", since focusing on the $25 bid since the guy couldn't spell Edelbrock or carburetor (is it mean to prey on illiterates?). I couldn't understand the missing vacuum ports or how I could use on my Dart, nor could a speed shop that sells Edelbrocks. Finally found it was a marine version and sold it for $175 on ebay right at the start of boat season when everybody finds their carbs gummed up. Bummer, since it looked brand new, but cash soothed the hurt. I love to buy new carbs just to play with them, then resell, especially when I find a deal.
