Im going to check engine oil after each use & see whats going on here & no more mowing tall weeds only my grass.
Thanks again!

Your engine is already 40+ years old, changing your brand of oil can't help it so much because he burn or loose plenty already, in old Harley air cooled V-twin we use to put straight SAE 50W to help them.(Less leak, better compression but a bit harder to start)
I don't know if anyone have try this in a K series engine and if it's a good idea but I never see one of those old HD throwing a rod because of high viscosity oil, they do it for lot of others reasons...
