I've come across a lot of Hatz Z790 diesel engines for sale in the local area... turns out a local AFB has them for sale on auction.
The engine is air cooled, 2 cylinder, and puts out between 18 to 26 hp or so, depending on how they're set up. They're pretty tall--approx. 27", so I'm wondering how they'd work to repower my JD420, and maybe, ultimately, my Dayton 3Z678 (MTD 995).
I searched the forum and couldn't find any information... has anyone used these in a repower, or have experience with them?
There's a YouTube video listed below that shows one running.
