You sure it isn't the Dooby Dooby Doo penguin in the back ground getting ready to pounce on you?

Is the Walbro really that loud? I haven't even got my car running yet so I haven't heard mine yet.

My walbro is pretty noisy too. There was a large thread about it called how loud is your walbro or something similar to that.
