My Husqvarna yth150 mower with 15HP Kohler Command engine Model CV15S Spec #41597, started acting like it was starving for fuel sometimes. I replaced the fuel filter,air filter, and the plug. This didn't help, it would run fine for a while then
it would start loosing power then catch up an so on. I had the
carb. cleaned also the fuel pump no problems were found. Just
worndering if anyone else has had this problem, an could help
me.
Thanks

I think what you are describing is what Kohler calls governor hunting. Engine RPM oscillates from low to high RPM. A service manual is available at the Kohler website for your engine. It covers all details of governor hunting. Most often a thorough carburetor cleaning will restore proper engine operation.
