Kawasaki motor Valve adjustment

I have a older about 15 years old LT180 it has a Kawasaki motor about 15 to 20 hp. I cannot find a tag on it to find the model #. Does anyone know where it may be. Also I need to adjust the valves that is one reason I need the mod. # does anyone have the specks on in & ex I did a search for a youtube video but everything was for a Briggs and that is all I have worked on. If someone could post a link it would help a lot. The other reason I need the model # is I need a new fuel pump. One thing I found was the valve adj is backasswards from a Briggs. The outside nut is the adjuster and the center screw is the lock very odd . I know it is hard to know the specks with no model #. So I'm stuck till I locate that.

Thanks in advance
Ken
