I'll have some pics later, but I picked a Kohler Magnum 16 yesterday. Has some oddities about it. Supposedly came off a zero turn mower. Here's the #'s:
M16AQS
711562
??15304153
The PTO end of the crank is nearly flush with the block and looks to have a bolt broken off in the middle of it. Also, a small taper there.
Flywheel end has a stub shaft adapter on it. Looks to be 1" diameter by 1.75" maybe.
I'll get out and take pics later this morning. It seems to have good compression. Has a PO modded Intake & carb. Also has a very nice though big muffler.
