stevasaurus 22,229 #2 Posted November 21, 2020 Those Kohler engines came stock with either .000 or .300 from the factory...depending on the bore. What did you have in there?? I don't know if .300 is available...you may have to go to .500. Anyway, you can get Kohler parts on E-Bay. How is the journal on the crank shaft. Do you have a small engine place or are you doing this yourself.?? Share this post Link to post Share on other sites
