Just be careful about closing the MPD to much. This morning I had a back draft when I closed mine.

I have never had a back draft, caused by closing the MPD, ... that I'm aware of.

If it were my situation, I'd ask myself: If the chimney was high enough? Is something else pulling air from the house, such as the furnace or an exhaust fan, coming on? I witnessed my upstairs curtains, suck in (in the fall, with window open), when my furnace started, in my 1880's house, which shouldn't be that air tight. After that, I added an outside air source for the furnace. I now also, have outside air source for the coal stove and the fireplace.

The other thing, which it might have been, rather than a "down draft", was the rapid ignition of the coal gasses, which is, essentially a "mini explosion" within the stove. This can happen, after adding coal, as the gases heat and build up, before "rapid" ignition. This will blow dirt, etc. out of every opening in the stove. ??

Might have a a mini explosion I'm burning very smoky bit coal.

Not had problem since then.

Yes, it helps to close the mpd somewhat after loading. The Coal seemed to last and burn better. I have to keep reading. It's twenty six below tonight but warm in the old kitchen. Not sure about the Lower air supply. I read Open them both when loading and then shut the top one. It takes me top long to full the stove though... Took me from six until noon to get a good bed going. I need to be quick...trying fire started tomorrow morning. The first night there were coals nine hours later but the second night it was out cold and unburned three hours later. Have to keep reading!

When, first getting it going, leave both top and bottom open ... most air through the coal. After that, close the MPD as permitted and then close the lower under fire draft for the correct burn.

I just watched William in white shirt sleeves again. He says to close the bottom almost all the way. Not the same stove but perhaps the same principle. Now that I am covered in coal from my efforts I'm very impressed with his clean shirt but I hope to improve. Lol. Clean coal, eh?
