Mellow Yellow has developed a hissing sound which seems to come from
where the throttle body connects to the air distribution manifold. I
heard the sound then localized it by listening around with a bit of
garden hose in my ear.

I can't tell if the hissing sound is normal, and I never noticed it
before, or if it new. Spraying carb cleaner there does not change how
the engine runs.
