What's your altitude? Carbs set up for elevations near sea level run rich in mountainous regions. A carb that runs right at Daytona Beach will be way rich in Denver, for instance, due to less air density at 5,000+ feet of elevation. Fuel mixture is calculated by the weight of the fuel and air, not the volume.
