But you know, if you've had the car for 16 years, and never had this problem before, and you don't see brown leak stains around the intake manifold, carb floats don't just up and change themselves after that long. You may have just got a tankful of gas that percolates off easier. If you happen to remember trying a new gasoline, then go back to the old gas. Otherwise, a 30 second float adjustment should fix it.
