NOISY ENGINE?

MY ST220 MAKES A WHISTLING SOUND WHEN OFF THE REVS,THEN GOES WHEN THROTTLE IS APPLIED, WHAT IS IT?
SCOTT, July 2008
sound is induction coming from split/perrished/missing vacum hoses on intake side of engine.usually 6mm-10mm black hoses like small coolant hoses.running ur hand over them sometimes changes pitch and can help find leak.if not its systematic removal till noise changes to find source
