In a recent thread, I provided a narrative of troubles I had with my LawnBoy DuraForce engine. The result was engine failure, requiring a new short block. The block arrived today by UPS. We finished our mowing route early today, and were home by 5:00. So, I started the install of the new short block and hour later. I work outside and a platform. By 8:15 a shower arrived and I had to pack up before I was completely done. I hope to finish the project tomorrow evening. I was surprised at the lack of lubrication in the cylinder of the new block. The walls are dry. Since I have a day before completing the install, and still have not put the head back on, I thought I would ask about preping the walls before attempting to start the engine. Since the walls appear to be without any lubrication, the first few strokes after starting could be brutal. Can anybody suggest a procedure to lube the walls before starting? Or, is my concern ill-founded? My thought was merely to rub the walls down with engine oil before installing the head. Yes, it would probably smoke after starting to burn off the oil, but at least the walls would have some lube on the first few strokes. Ideas or comments? Thanks. P.S. I have taken some pics of the procedure to tear down and do the install. When I have a bit more time, I will post some of them, with narration, so that it may help somebody else who is considering such a project.
