This is the first time the engine had run in many years. She has just undergone a complete stripdown and rebuild. Here she seems to be running much more strongly on cylinder 1 hopefully this will just be a case of balancing the 2 pumps, either that or it is a problem with the pump or injector on number 2, compression is good. The reason she didn't start on first attempt was me! I had the external governing spring too slack.
