Found some problems with the ka 6, grates had been removed by owner and never resealed at the upper end. However, the coal still hangs up. it did slide down but as a complete sheet, 2" thick as wide as the grates and 1 continuos piece into the ash bin. Have tried 3 different brands of coal, Cornwall, Reading- bagged and bulk, and hazleton shaft. to no avail. The guy's wife wants him to throw it away and I'm gettin to that point myself.
I am unable to get over 400 stack, even with buckwheat. All suggestions are appreciated. Bobo K
