Went out to take a look up the chimney to see how I was making out, to be sure no creasote was building up. Noticed around the cleanout door there were places air could be getting in. So I built a fire and took a lighter and worked my way around the cleanout door. It was sucking air like crazy. Siliconed it up and the stove, which I could not complain about anyhow, is a heck of a lot easier to control. Drafts much better seems like. Never knew a little air getting in would cause trouble.
