Tim, be aware of the engine rotation, an engine mounted behind the mill will be turning the wrong way, as they are designed for tractor PTO. You can set the engine on the sawyers side and have proper rotation, but if your milling alone you will have to walk around the engine. If you can choose a diesel with a variable speed governor not just a limiting speed one you will be much better off. Somewhere on the internet I have seen Belsaw manual free to read. Frank C.
