"Here is a pic of my tent stove. I have a heck of a time getting this one to work right. Any suggestions I could do to modify it. If I leave the door cracked it burns fine, a little smoke comes out though. "


If cracking the door does the trick, than you aren't getting enough draft, or the air intake isn't providing the oxygen where it is needed. Your intake on the door looks like it is big enough, but I would put the intake lower so the draft is flowing up through the fuel. My exeperience with stoves (mostly larger home, not portables) is that those with a lower air intake burn much better.
