The engine in question was mounted on a teststand and all hardware was also "out in the day" and very exposed to cooling air, nothing got hot. Anyway on both engines tested they both started and ran flawless during first day of running and then suddenly the next day nothing at all will make them run??? Both me and Yallaair are out of ideas other than that the ignition module does not last more than a couple of hours of running. Are we the only ones having problems with this engine???
