...About a week ago I added 1" of kawool on top of the baffle so the secondary would warm faster...
You did what? You mean over the top of the metal baffle plate and the firebricks? My gosh, if that's what you did, then air can't even move through the stove at all like it's supposed to. Get that kaowool out of there, it has absolutely no business being in there. Don't try to second-guess the stove designers...they're pretty smart.
