I trouble shot engine. The starter turns the crank, but the output shaft (at the bottom) doesn't turn. I put a socket wrench on the output shaft, and the flywheel turns. I took the spark plugs out and stuck a long screwdriver into each cylinder and was able to push the pistons all the way to the bottom. When I turn the flywheel or the bottom shaft, the pistons do not move. They remain at the bottom. Any guesses? Or conclusions?
