My grandson has a Cub with a Kohler 10hp 241AQS engine. He wants to rebuild the engine/have it rebuilt, but he has disassembled the engine and wants to have the engine bored .30 over. He has tried to remove the flywheel, but there is a "rope start" pulley attached to the front of the flywheel. Any idea how to remove this to allow the removal of the flywheel ?
