This is a picture of the midwest single rotor.
Are they using a single balance weight on this engine, or is the photo missing the other weight?

Missing the other weight. Interesting combustion chamber eh what? :-)
Note the needle roller bearings in the rotor. This is why they
must limit the RPM to only about 6000 RPM. If they went to plain
bearings and a high pressure oil system this little jewel ought
to develop twice the HP and run at well over 10,000 RPM.
