They are adding BUTANE to our gas now to get rid of it. Before the EPA the refineries just burned it off It only causes problems in an open fuel system as in carburetors. The zenith carb is cast iron and obsorbs a lot of heat. The after market carbs like the tilli not so much. The 1/4 inch spacer should help.
