Just what 68 said. The vacuum gauge will get your mixture right on without having to rely on your ear.
I'd grab the carb with the electric choke. It's what I have on mine, and in my estimation, its just a simpler setup. No linkage to bend/adjust, don't have to worry about the choke stove getting gummed up when your inner intake bolts start to seep oil, and they're easier to adjust when the weather changes. Just loosen the screws holding it on and rotate. Just need to run a key on 12V wire. And if you want to be really trick, there was a member who remarked that he wired his choke in through his oil pressure wire, so it only got 12V when the engine was running, not just when the key was on (so you don't have to remember to make sure your key is in the OFF position when you don't want the choke to heat up).
BHyatt, the original setup that worked well was a 2 barrel, which for obvious reasons isn't acceptable...
