Searcher60 208 #1 Posted April 19, 2017 How can one tell if a Kohler engine is really a K321 or K341? Is all the tin between the two interchangeable? Is checking the bore the only way? If the bore is 3.70, and the piston is stamped .020, then I would guess the engine is a K321 bored out .020? Thanks Share this post Link to post Share on other sites
