Good Morning!
I have a Kohler Command 16 on a Craftsman riding mower, the Kohler info has been wiped off the sticker so I don't have much information. It first started that it would run and shut down like it was starving for fuel. I replaced the fuel filter & carburetor. Now it runs at what seems to be half throttle and makes some noise as it runs. I took the valve cover gasket off, rockers are tight, rods are not bent, but it seems when its running both valves are opening and closing at the same time. Compression gets upto about 90psi and drops almost immediately when I stop cranking. Also, I put a new plug in, after a minute or two of running the plug is completely black with pretty thick build up.
