prondzy 3,889 #1 Posted December 10, 2014 I just thought id share my story, I am going to be rebuilding a 14hp kohler with some modifications and I decided I wanted to make the 1 1/8 exhaust valve a 1 3/8 valve which requires a larger valve seat, I was sticker shocked to find out that kohler gets $50! so I started shopping around and found that trough Summit Racing I found a 1 3/8 valve seat for $12 shipped to my door. SCORE! so sometimes it pays to shop around! 3 Share this post Link to post Share on other sites
