[Steam-engine] burning coal-

[Rupert Wenig]

Hello Andrew,
	Have you tried a different coal? We have two 1/4 scale cases here. One 
owner refuses to burn coal so he burns wood. He gets about 1/2 hour of 
running before he has to clean flues. The other owner imports his coal 
from some where in the eastern US. I'm not sure what type of coal it is 
but it is a metallurgical grade. He can run all day without cleaning 
flues. Hope that helps.
