Short story- carb float stuck open; washed engine down. All connecting rods loose; cylinders 6/8 were worst. Images are of the connecting rod cap; bearing inside/outside; crank connecting rod journal for cylinders 6/8. The main bearing caps are tight. Crank was turned about 1/4 rotation to make removal of connecting rod cap for cylinder 8. Did not need lot of effort to turn it, but then again, I'm not an expert.
