Kawasaki FR691V engine from an Exmark Quest zero turn mower. The engine has compression, one cylinder is 125 and the other is 140. The starter wasn’t strong enough to start the engine on both cylinders but I started it on each cylinder with the spark plug removed from the other cylinder. The engine ran ok but was loud as the muffler is broken off. The oil was a little milky looking. I think at worst you could put new rings and gaskets in it and have a good engine. You may be able to flush the crankcase and replace the starter and be fine. The air filter was crumbling so I removed it before starting the motor. It comes as pictured. I got this off a mower I got at an estate sale, I have no history on it.
