Sometimes you will run across a motor with a bad center crankshaft bearing . The crankshaft bearing surface will be pitted…. I describe this sound the same as a kid on a skate board rolling down the sidewalk. When a motor gets put away without fogging it, in the right kind of environment, this can happen.
