Hello all can anyone tell me how to set the valves on this 23hp Kawasaki i read that it needs to be done every 300hrs and this one has 1100 and i doubt its ever been done. I just bought this mower and it has a "tick" at the valve covers i just figure they may need adjusting. RestorRob if you see this do these adjust the same as the 24hp Briggs engine you just helped me with? Also does anyone have a diagram that shows where the carb and choke linkages hook up to and the springs? I had a spring come off and i belive ive got it in the wrong place. This is on a John deere 657 any help would be appriciated it! Thanks!
