That is a heck of a project you have there.
It would be nice to get a back-story on this engine such as where
you found it and how long ago, to start. Was it stored in a barn?
Was the owner a 'character'? All cool!
Hopefully, Jensen will be able to supply any parts you
may need. They are also good with advice and help when needed.
For me, they fixed an unfixable engine.
Keep us posted,
