Sorry, I did not see you reply. we must have been typing at the same time. Taken: what you say makes sense. The engine was rich and hard to start. However the leak starts from the moment i pulled the cord the first time it seems. It seems that was the problem the previous owner had. I got it completed bathed in oil/fuel and had to give it a good clean before I could put my hands on it. I also suspect the two big gaskets in the photo may need replacing.
