Additional thought: The choke on most carbs is dual-action. It increases the idle speed as well as the mixture. One possibility is that the idle screws need to be turned in to increase the idle speed when the choke is off. My experience is that the idle speed needs to be at least 500RPM to stay running at all. With your engine mods (especially the cams), it may have to be higher than that.
