My Rochester Monojet carb squeals loudly out its throat when idling. If I give it a little gas the squeal goes away. I first thought it was the generator bearings going out.

Is this normal? I have one of those small after-market air cleaners on it. Will a better air cleaner muffle the sound?

Thanks.
