I have 90 PSI cylinder pressure on a 1974 H3. 110-120 is what it should be. At what point do I put in new rings?

Kohler engine info is online just google it
I think 150-180 possibly when they are healthy . Your almost half .

I looked in the JD repair manual and it said normal pressure was 110 to 120. This one is at 90, I think for the time being I will just run it.
