Running doesn't damage engines. Starting and stopping is what damages engines particularly short trips. I once worked with a couple of guys who owned little Russian aerobatic airplanes (Sukhoi Su26 or 29 IIRC) with M14P 9 cylinder radial engines. I was told that in Russia these engines are used on generators, air compressors, water pumps etc. and running on LP gas have been running continuously for 20 years. I'm sure IAV and Elio can better the Russians workmanship.
