older exmark lazer z

I have a older exmark(I think 94) with a ch22s 66529 kohler. I took a compression test on it this afternoon, the engine was cold and both cylinders were 100 lbs. I don't know what these should have so im hoping someone can enlighten me, it doesn't seem to burn any oil but now that the mowing season is almost over im just checking the general health of the motor and if I need to tear it apart I have the winter to do it. thanks. wnk
