Thanks for the posts guys, i kinda new that the Austral Honda guy didnt know what he's on about. Just wanted to make sure.

Beeza: I cleaned it with carby cleaner today, but I havent checked to make sure its working yet. It looked a little worn and old. I'll check it tomorrow, but I doubt its ever been changed in the engine's 170k life.

I checked it before cleaning it, and i didn't hear any clicking sound when i squeezed the hose.
