I felt I should clarify that my home is not new or air tight. It was built in 1978. Most of the threads I have seen about fresh air intake have been related to a house that is too tight, or has other appliances that are pulling to create a negative pressure. In my case I believe it is due to the leaks in the house that was causing a negative pressure in the basement.Okay, I got the fresh air supply hooked up and the difference is dramatic. Before I had to leave the door open or the fire would never start and smoke would billow out of the air intake. After adding the supply I can close the HC door and the fire continues to grow. The fresh air intake has a lot of airflow so it is like putting a blower up to the air intake. Some smoke started to creep through my stove pipe so I sealed that up as well. I'm pretty sure this should resolve it.
My draft fluctuates between -0.03 and -0.07 when the fire is going after a while. Before I start it I have barely any draft. Granted the inside and outside temperature difference is only around 15-20F right now (It doesn't get colder until morning). AFAIK that will impact draft during ignition.
