I bought quite a few Yanmar small air cooled Diesel engines for various applications at ADOT. Very unique engine; it would run either way that you started it. Very smooth with very little vibration. However, those small air cooled Diesels were "throw-away" engines. It was less costly to replace one than to overhaul it.
I bought a mix of Yanmar and Kubota liquid cooled Diesels for light towers and other machines; they seemed to be about equal in those applications.
