mid moe allnighter won't draw right

We recently bought a house in tenn, so we took our blaze king kmj 302 down there and replaced it here (indiana) with a mid moe. This thing (the mid moe) has something wrong with it, we have to have the door cracked for it to even stay lit. That's with both air intake knobs all the way open, we have run a wire through them and blown compressed air through them, they are open. With the door ajar about an inch or so you can get a good flame going, then shut the door and the fire dies down to nothing. Was wondering if anyone had experimented with taking off the baffle on the inside of the door, it looks like that's what directs incoming air over the glass to keep it clean.
