Wondering why I could not get the stove over 300 deg, increased feed, still no good. Seems the combustion blower worked it's way back in it's mount just about cutting all air to the grate. Quick fix just bent the tabs a tiny bit on the blower so it fits in the tabs nice and snug. Probably should have a set screw, go figure???

A tip here. The cup shaped fan blades of a squirrel cage can pick up lint and dust in the belly of the cup. If your blades are full of crap it can cut the air delivered by 60% or more.
