You have klinkers. Time to aggressively shake or shutdown & clean out. Take advantage of the warm air.

Red ash coal will fuse, especially at upper temps :x In a hand fed white ash coal is better :D I learned this the hard way, WAY before forum's such as this. :oops:

I got home tonight and I shook the hell out of it and clinkers it looks like all the smaller stuff fused together looked like it just melted into a blob but it is all cleaned out and running smooth again guess I will have to screen the smaller stuff out.
