The sound kinda sucks ... and so does the video!
My Kodak "point-and-shoot" had some kind of noise-cancelling feature, and that is pretty much what you really hear.
I should have had someone there to do it that wasn't quite as involved as I was.
This was the intial break-in ... the one that wiped a cam lobe, so consider it to be more like a "how-not-to" video.
I didn't video the current configuration, but it now has quite a bit "lopier" idle and really snaps when you blip the throttle.
