This is a Lauson model RSC514-7. It is in excellent condition. The bore shows only .001″ of wear. All that was needed was to clean and re-adjust the carb. and it took right off. Of interest, at least to me, is the shielded ignition and the lack of a governor. Supposedly, this engine would have run an aircraft cabin heater or an APU on a military aircraft. That explains the O.D. green paint and the safety wire on all the fasteners. The following pages are related to this engine.
