Hi Paul, Do you think there is a way to produce 85 hp

And what do you think about an engine that did not run

You might be able to do it barely with extensive porting
or a peripheral port.

Good luck on that engine that did not run for eight years.
You will probably have to have the end housings lapped or reground.
Don't try to turn it over as you might damage it more.
Just take it apart and inspect it.

If we can get 180 HP from a two rotor 13B  why not half that on a single?

On Junkyard Wars they start old engines without a second thought!

A 12A is a smaller engine than a 13B Jerry.
