RJL MECOA claims to have the rights to that design, but there's squat about that engine on their site.
Other than reiterating the lore that almost all Deezil engines were so badly made that they are impossible to start and run successfully, all I can say is that with a real vintage prop it would make an interesting curiosity to put on your workbench. Trying to run it might put you off diesels permanently, I'm afraid.
If you want to disassemble that engine for inspection and cleaning, I think we'd all be interested in a peek at the internals and your observations. Heck, if you can get it to turn over smoothly with decent compression, I even want you to mix a pint of "old English" mix and give it a few flips. All you'd probably be out is the cost of a wooden 9x4 and whatever you need for the fuel.
On that less than cheery note, I'd love to see you acquire a better engine for a first model diesel and come back for help with a project that will be a success.
