Today was the first run of the single rotor with one final configuration
compound side housing. No problems observed, except for a clogged carb
jet from laying around for 6 month. No more cast iron between side
housing and rotor housing (picture).

This is the side housing I showed at last Octobers Shady Bend meeting.
MAP was at only 20", which is all I can do with the present setup. Since
there is no dyno in my real world, I will have to think about reworking
the test stand for running the engine with a real prop.

Congratulations Richard. I have added some old pictures of the
work you are doing so the new people can fully appreciate what you
are dong with two piece end housings.
