While disassembling my Kohler 220 motor. I removed the Kohler 10hp shroud only to find K301 on the engine block. So I guess it is a 12hp in disguise. Just one more surprise on this frankinstine tractor I picked up. Good news is I dropped the block off for a rebuild and they can start in March. Sheesh. Got plenty of time to clean the three inches of oil grunge off everything else .
