rmaynard 14,950 #3 Posted October 5, 2011 The Kohler service manual is available at the Kohler Engine website or you can download a copy from MyWheelHorse.com. If your machine shop does not have a copy of the engine specs, you might want to look for another shop. Standard bore is 2.938 Share this post Link to post Share on other sites

Likewise the parts manual, another very useful document for this project.
