I'm ready to purchase a carburetor for my 1980 Spitfire (Federal). Right now I'm pretty well sold on the Weber DGEV, unless somebody has a better idea. (The original ZS carburetor is long gone.) I live in the Willamette Valley, so it never really gets that cold in the winter (it's rare to get below freezing), and it doesn't get that terribly hot in the summer -- 90 is about tops. I do, though, have mountains all around me. I'm not sure if any of that makes a difference in what carburetor I get. On the Weber, I know that I can choose either water, manuel, or electric choke. Which is best? Thanks!
