Ive got a 1996 walker mtghs 20hp kohler that has broken connecting rod. Ive found 2 older mowers one is 95 and one 93 both have a different style 20hp kohler. Looks like they are completely backwards (gas tank, muffler). Crankshaft on mine comes out flywheel side and theres are on the opposite. Just wondering if anyone knows if the motors will work on mine?
