Sure sounds like it’s off the one carb and affected by how hard you push on the snail. That side also not pulling as much vacuum.
Suspect leak at a gasket that is whistling, squeaking, or whatever you want to call it. Sort of like blowing air over a blade of grass trapped between your thumbs as a kid. Alternately is it the air filter housing loose on top of carb and squeaking and changes pitch when you press the snail harder into the velocity stack loading the air filter housing differently? Those are my best guesses based on the video. |
