    I was hoping it wasn't bearing noise. Anyone else have input?

    you have the d plate right?
    it seems like you have a sticky carb, or an air leak.. just comparing the 2 vids.. mine goes back to idle real quick, while yours seems to "hang"

    All I hear is the compression pumping as the engine slows to a stop on both of those. I've worked on 2-stroke machines with sketchy lower ends and a bad bearing usually makes a pretty loud whining raspy type noise that's noticeable at all RPM's. Imagine taking a stick and dragging it quickly across a concrete sidewalk and then add in some whining noise. That's the best I can describe it.

    Yes I do have a d plate in mine. I also have riva flame arestor and my carbs are jetted per osidebill sepcificatiins. Not sure if maybe that is changing the way it comes down from rev-idle speed.

    Could it be starter bendix? I've heard that noise before.
