Engine running again (with video)

The little 15hp engine and the gearbox are back where they belong. The rubber gaskets between the cilinder head rocker tubes and main block are replaced, the rear main seal is replaced and the valve cover gaskets are new. I had to weld the cowling metal in several places because it was torn or otherwise broken, but now it looks like a decent engine again. At first my plan was to not touch the engine at all because it was running beautifully. The plan was to just put it back in, but when it is out, it seems smart to do some preventitive maintenance.
