I have a 17 year old Cub Cadet lawn tractor with a single cylinder, 12.5 hp, motor with ohv. I have no info on how to adjust the valves. I removed the valve cover on the very top... That's as far as I have able to go. Engine has about 15 lbs. of compression which is low. It is very hard to start but once it's running it is very strong. How do I go about adjusting the valves?:confused:

Hi,
I did not see your post You want TP-1288 (K-361) manual. Fortunately Kohler is forgiving of people posting manuals, so a link to many of them (an incredible number) is:
Kohler Manuals (http://www.asberry.net/Kohler.htm)
And picture below.
Peace,
