Didn't notice this on my last motor but I can hear this whine coming from the motor that sounds almost like a turbo whistle. Motor is having performance issues and cannot diagnose the issue with Briggs or local Briggs service center. Any ideas?

Check for a vacuum leak

Back at shop, possible blown gasket I guess?

Mine does it but i can barely hear it when coming off the throttle. Really gotta be listening to hear it though. Its done it ever since input the marsh mellow on, never had any issues though and i just went through and check everything in it a month ago.

Noticed mine making a whistling sound yesterday. I can hear it the most when it's in neutral. 37efi gtr with about 5 hours. Kind of figure it's normal since I would hope there's nothing wrong with a brand new motor. It has a warranty so whatever.
