In this video I run 3 diesel model airplane engines. Two of them are new (OTM and FROG) and had never been run. The PAW is the first diesel I bought over 30 years ago. I bought it from DR. DIESEL (Eric Clutton) and in trying to free it up from a completely gummed, stuck condition, I broke the connecting rod. It has a new connecting rod and this is the first run after making the repair.
