Yes, what Bob said. I turn my GAV 1 to 1 1/2 turns open for the first minute on a cold engine, and if the engine starts to die after a few seconds on a cold start, then I also give the choke a quick pull and release. I let it idle about 1 minute then close my GAV and drive away. Most people leave the GAV a quarter turn open, and I could also because it runs the same as when I close it.
