Tim, 1912's are very hard to find and if the price is right, go for it. It prolly has the B48G engine. As you know they are the most expensive to repair but was one of the best air cooled engines ever put into a Cub....my opinion. Look over on WFM and see the money those rich boys spend on repairing those old Onans rather then drop one of todays repowers in it. Nothing has the sound and power as a good running gas gulping Onan. These engines did have issues with weak rods, valve seats & carb/intake problems but I would definitely look at it and if you're not interested let one of us know. IIRC the front pto's bring around $300 used. Good luck and bring us some pics.
