O.K. heres the report: I just stumbled accross an product report on the 160 twin by Clarence Lee. Yeah good ole Clarence

he lists the rpm range for all the props listed in the manual

the 18X8 turned 7400 for him so I am at least 1000 off. So back to the engine to find the culprit !!!!!!

did I mention I just love to work on engines !!!! I mean why go fly when you have a an engine just waiting to be torn apart ??
