125cc commercial mower engine from a Snapper Hi-Vac. They were a pretty high-end machine, but I hate self-propelled mowers so it's getting parted out. Pressed-up crank, steel rod, big bearings. Under-ported and revved to last forever. I had to tap the extra carb stud holes 90 degrees off the mower ones, and put the Mikuni on for upright use. Muffler got flipped, pull cage rotated, internal flywheel brake removed. Starts right up and sounds good. Easy to mount, once I get a round tuit. 7/8 shaft (22mm?) , semi-bummer, but it's keyed and I could put a sprocket on and clutch the jackshaft.
