Smoke and fumes coming out of the auger in your coal bin could be due to a few possible issues. First, ensure that the auger and its connections are sealed properly to prevent any leaks. Additionally, check for any blockages or obstructions in the auger system that might be causing backflow.

The draft measurements you mentioned seem reasonable, but it's essential to confirm that the entire venting system, including the chimney, is clean and free from obstructions. If the problem persists, consider having a professional technician inspect and service your efm coal stove to identify and rectify any underlying issues.
How do blockages in the auger cause a backflow? Seems counter intuitive. Blockage means no flow.

Blocked is different than obstructed at the inlet. You are right that if an auger was plugged solid no gasses would go through, but what usually happens is a big piece of coal ends up at the mouth of the auger and prevents rice or buck from flowing in. The auger ends up mostly empty, and gasses can blow back into the coal.

Does it happen only when it cycles? Or can it happen continuously?

Are you running an extension or just a short auger?

We have not heard anything from this fellow since February of this year.
I hope he was able to fix his stoker operating issues.
