Hi, I have a National engine (from all the info people have send me on Smokstak, UK stationary engine, and lister engine forum). Still unsure which exact model it is. IIRC spec could be DSSAGP ? Is this a DSSH type engine? Any manuals/starting procedures out there? Here's a picture some sent from a unit at the Anson museum: I dont have the carbeurtor for it....so I plan on running it on diesel for now. Any help would be greatly appreciated. A.S.
