fter heating the crankcases and a quick tap with a rubber hammer I now have a free crankshaft.
Although rust on the surface, the bearings have responded well to soaking and oiling, so much so that I'm going to rebuild using the old bearings.
If it doesn't work, well I have a spare engine on the way.....
Inside the crank cases was full of crud as the picture shows.
and this is a complete, stripped engine!.
