persof 14 #1 Posted February 15, 2010 The Kohler Magnum 12HP in my Wheel Horse is the same weight and has the same stroke as the Kohler Magnum 16HP. Can I bore out the cylinder and fit and install a pistin from a 16hp engine? Or are the 16hp Magnums a different block? Thanks Francis Share this post Link to post Share on other sites
