Teeth missing or worn on the ring gear shouldn't cause the engine to turn hard or keep it from turning by hand. Its just used to provide a mechanical advantage for the starter for cranking the engine. Pull starting isn't going to solve the engine problem when you can't fully rotate the engine one complete revolution by hand. I would pull the head and see if there's a scored cylinder. Will the starter spin the engine freely with or without the plugs installed? You may have a spun bearing. You need to look at your valves to make sure they're all free and moving when the engine is being turn since one may not be fully closed.
While you have plugs out of the engine you need to bring No1 piston near the radiator to top dead center on the compression stroke. Hold your thumb over the plug hole and have someone hand crank the engine until you compression against your thumb. You can drop a "large" handle screwdriver on top of the piston and then watch the screwdriver rise as someone slowly cranks the engine. When it quits rising your No1 piston should be at TDC. Your timing mark on the damper pulley should be aligned with the pointer, pull the distributor or mag cap and see where the rotor is pointing. It should be at the No1 plug tower. Check the valves on No1 cylinder both should be closed. Hal PS: Let me know what you find.
