Re: Whistle coming from carb area?

All three of the last Demon carbs I ran had the "whistle" and I chalked it up to the design of the venturies and boosters. There were no vacuum leaks on mine. That was the least of my worries, the eye-burning rich idle circuit on each of them was the nail in the coffin.
