Found a Hapi 1835cc VW Aero Engine that had previously been installed in a Sonerai. The owner removed the Hapi to install a 2180 cc VW engine because of the high density altitude his airport in Utah was located at. He stated the performance increase was not worth the cost
This engine ran for a reported 200 hours, there are no log books, It came with a Zenith updraft carburator. No ignition system.
