I purchased a 682 at the Florida Flywheelers last week. It had a 16HP Briggs M#303447. Drive shaft was jury rigged off center causing major vibe at engine. I know this came with a Kohler KT17 which I have a good one. Does anyone know what Cub used the Briggs. It says Cub Cadet on air cleaner. I know how to reconfigure drive shaft for the Kohler. Does anyone know what adapter looked like for Briggs to Driveshaft coupler.
