Looking for a Kohler K-531, or K532 for awesome project!

[esoteric engine fever]

Hey everyone! I'm looking for a Kohler; flat twin cylinder engine in complete, or near complete condition. Basically if it can get running with reasonable amount of effort I'm interested in possibly acquiring.
If you happen to be aware of other opposed, air-cooled twin engines, I'd be equally interested. Any help with this endeavor would be the upmost appreciated.
Thanks,
H. Smith

look old rv generator sets with kohlor magnum engines. they have a tapered crankshaft end but you can buy an adapter to change solid straight shaft'
I am in the same boat and wish you luck
