moe1965 750 #1 Posted December 9, 2018 I started working on the 854 today it has a 8 horsepower engine the exhaust valve is stuck open I thought I would just clean everything up the best I could and shoot a little bit of Aero Kroil oil in there and give her a few Taps now and then and see if it freeze up any suggestions 2 1 Share this post Link to post Share on other sites
oliver2-44 10,073 #2 Posted December 9, 2018 That's definitely where I would start. Since after you get it free the valve clearances shold be checked, i would pull the breather and shoot some of your solvent from the bottom side as well. good to see you working to save that Kohler 3 Share this post Link to post Share on other sites
