Been there and done that. You need to go back to basics. Take the center apart and make sure that the float is set correct and that you don't have fuel creep past the float. Make up some block off plates for the end carbs and try running off just the center. If the smell goes away and it runs fine, chances are that your end carbs are leaking and causing the car to run rich. You will need to address ill-fitting throttle blades on the ends. If the throttle blades on the ends are leaking, you will pull some fuel out of the end carbs, making the damn thing run rich. Have you pulled plugs??? If you had a wide band O2 sensor fit in the exhaust, it would also tell you which way you need to go. With out that, it is trial and error.
