1. Is the botton of the cylinder supposed to be pitted?
2. Are the valves supposed to have grooves?
This is the 1973 816 limited slip with steering brakes I picked up that had the broken shifter fork. After replacing the shifter fork I used it to mow the grass, 3-4 acers. I started to notice it used oil and had noticeable blow by, also I couldn't keep the oil clean. This model cck has the breather straight to atmosphere which makes the blow by more noticeable, not so much visually but you could smell burnt oil. Other than that, it honestley ran great. Knowing it was pretty worn out I imagined some wear inside but was surprised to see the pittting and worn valves.
If it had enough power to swing a 50" deck and pull a 60" tow behind in this condition I cant wait to see what it is like rebuilt!
