Very cool Gary. I think you will enjoy this little engine.
I have the “wood burning” version that also came from Royce when they were in production. I was never clued-in on break-in procedures and it had a pretty serious hitch in it’s giddy-up when I first ran it. Accucraft had me send it to a servicing dealer (another well known name in the live steam world that I just don’t remember. Dave Hotman maybe?) It ran better when I got it back, but I’d never describe mine as a Swiss watch (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-surprised.gif)
@Pete - How come I never heard of that heat shield idea!!! Mine doesn’t have a lot of hours on it but I do know the smoke box gets pretty hot. It will smolder a small chip of coal I throw in for smell. I probably have one of the few wood burning locos that smells like a coal burner when they go by! It’s so hot that I can’t keep a brass number plate to stay glued (JB-Weld Hi-Temp) to the original number plate. I suppose I need to look into that shield mod.
