I don't think so. Every carb whistle I've ever had has been a leak around the base. While the whistle is whistling, if you take a rag that is soapy and sopping wet and press it hard against the base of the whistling carb, and move the rag around so you press it against the entire perimeter, can you get the whistle to change its tone, even just a little?
