At least the stove works and is keeping us toasty.
Shweet - Oakies are great ! Inexpensive Oakies are even better ! Now if they're the Douglas Fir 'edition', you scored way big !!
Convection air flow in a house is a weird thing. When I start my vintage almost 40 y/o Vermont Castings wood stove up, which supplements our pellet stove in the farthest away 'L' room of our "big house, middle house, back house, barn" connected floor plan farmhouse. I have to crack a specific window in the wood stove room to get it to draft and keep from smoking up the house, but only when the non-prevailing wind is blowing from the south or east.
It must create some sort of 'eddy flow' of air current, either through the house walls and / or over our multi-directional roof line and down the external chimney, that then downdrafts the stove. Turning on the bathroom or kitchen exhaust vents, which are the rooms on each side of our wood stove room, will also back draft the wood stove (but not the pellet stove) when it's starting up and the chimney is cold, but then there's no problem once the flue warms up and drafts better. Go figure....
Walk around your house on a 'blowing like stink' day with a lit incense stick and a toilet paper streamer and you will be amazed at where the drafts and convection air currents are going, even in a relatively new tighter house than mine certainly is. Try cracking a window in different places in the room that your venting goes through, and the room the stove is in, to see if it helps clear or at least minimize your smoke start-up smell, at least until it gets definitively fixed.
Knowing our houses natural air flow patterns is what helped me to better figure out where to put floor fans to move the cold air back towards the stove rooms, and how to best use ceiling fans to augment the natural air flow and better equalize the house temps.
Alternative bio-fuel burning seems to require 'eternal tinkering', but that's at least a good bit of the challenge and satisfaction of it !
