Hi there
Drifting off topic
I have never seen a big diesel running.
I would like too because I find it interesting that in my youth, (1960's) engines like the AmCo 5cc diesel were considered the biggest one could go, and even then they were considered a bit of an oddity and not commonly used.
Diffucult starting and vibration / rough running being the reasons quoted then for there unpopularity.
However I know that PAW now manufacture 10cc (.61) diesels, and many like yourself are very happy with their big, converted Glo motors.
I wonder what has changed to make them useable and popular these days ?
