I mean this, when I am a little less busy, gonna try and get us all to design one. Then chip in and have it made. A not for profit thing but not like an existing and already mass produced engine could not be adapted.
Really, need a plate, possibly a clutch and 4 extra holes in the base and bammm, MB engine. Every thing else is already cheap and available.
Dang, now I am getting excited about doing it. I once got excited about having a bushing made and 20K later, I am really happy about it. It's still unfinished but hey. snicker......
