I am running my eko 40 now for the first year, and I am trying to fine tune it. I have read the sticky on this topic several times, but I am still having issues. I have adjusted my primary air intakes to 9MM as recommended in the manual, I have adjusted my secondary intakes to 3 turns, and I have my fan opening set between 1 and 1.25 inches at the widest part. The fan is also set at 60%, which seemed to yield the best results. The problem is that I am still getting lots of smoke out the chimney when gasifying, and my flame, although whitish-bluish, is small...not filling the entire combustion area as it did when I had the factory settings. The problem with the factory settings was that I got so much creosote buildup in the loading chamber, it would cause the gasket to stick to the opening or pull out of the door completely when I opened the door, and the bypass flap would also stick shut. This problem seems to have gone away somewhat with the new settings. My wood moisture contend is 18-20% consistantly. I am not sure what to do. Is it better to have the smaller blue-white flame or the larger yellowish flame? Any suggestions?
