[Big hammer]

Use the rope trick, with #1 and #4 pistons down push 12 feet of 1/2 poly rope on top of the piston. You’ll need to use a stiff wire to push the rope over the pistons. Turn the engine over by hand compressing the rope, put a socket over the crank nut and then an extension and long breaker bar turn the engine. Don’t use the starter it has to much torque and you might bend a connecting rod .
