Oh okay. I have this model of saw and that hasn’t been an issue but I suppose that’s a thing that could happen.

Why let the blade spin down before lifting it up?

We’re you using a reducing kiln or something that’s burning gas the whole time? If not, and you’re just burning the material, then I’d argue the carbon you released was destined for the atmosphere already, you just helped it along but also locked a bit up in biochar.
