Well I finally got around to making up a dedicated steel frame and hanging a 180 pound hay bailer flywheel next to the JD175 flywheel directly coupled. First light was last evening and it looks like it may be a winner. Ran like a Listeroid at 500 RPM, except that it was smooth as silk and no vibration. From 500 RPM it takes about a minute to come to a stop after closing the fuel rack!
I have started a thread specifically for this project/experiment. I figure this is another way to increase fuel efficiency! You only have to actually run the engine for 12 hours to get power out of it for 24 hours!
