It may seem straight forward to the two of you, but on some Kawasaki engines you have to remove the shroud and flywheel to access the starter mounting bolts. That is the reason I asked for numbers. I also requested unit numbers, because in the past I have found that how the engine is mounted in the unit will affect how easy it will be to get at the starter. Plus, if I had numbers, I might be able to provide the OP with a service manual to help him out. Guess I'm over thinking this one.
