I originaly used a pair of stock 1850s. Two mods are necessary.
#1 You need to connect the vacuum cans together. You can buy the kit, but what I did was to drill and tap the covers and install 90Deg grease fittings with the spring and balls removed. It was kind of neat as teh fittings faced each other, so a short rubber tube was all I needed.
#2 The idle circuit is designed for single carb use. You need to restrict the idle passage or you will probably wind up with all 4 idle mixture screws all the way in, which works satisfactorily.
Eventually, I had Pony Carbs fix me up a pair of new ones. They seem to work the same as what I had, but I do have more range adjustment on the idle screws and they wound up somewhere betwen 1/4 and 1/2 turn out.
