Default Re: Whistling Power Valves

I just went thru this. I rebuilt the carb on an engine on my test stand. Boy, did it whistle. Mentioned it to Walt Dupont and he said to check the gasket between the main body and the throttle plate body. Flat filed the surfaces and put a new gasket on. Whistle gone!!
