I have a 2011 Husquvarna MZ5225, with a Kohler engine, it started bogging down today , like it only running about 1/2,throttle, but it’s wide open, any suggestions?

First check that the cable clamp on the engine has not come loose so it is in fact set to 1/2 throttle

No, throttle cable is fine, engine running very rough.
