In this video I show how I use a leak down test to diagnose the issues with an older Ferris mower that has Kohler CV25s engine.
This mower was brought to after someone else had made attempts to fix the issues. When I got it the engine had the valve covers and rocker arms removed. Also one lifter was taken apart.
I reassembled the lifter and engine to get start the engine and get an idea on what its problem was.
Hopefully this video will help you out if you are having a similar issue. A leak down test can easily help diagnose several issues. Valve issues, leaking head gaskets, or worn piston rings can be detected by doing a leak down test.
