I have an old Yazoo/Kees ZT Max 42" mower that has a Kawasaki motor that needs a new carburetor but the tag is worn off motor and I do not have the model no. of the motor. I bought this mower from a friend who acquired it with purchase of house. This mower is about 15-20 yrs old, does anyone have this mower and can tell me what model motor it has or where else I might find the sr. no. beside the little white tag on the motot?
