If you are trying to move the Engine sprocket with your finger as the clutch is pulled in... Then... Good luck.. you must have super strong Fingers... Can you say Paul Anderson? If the engine is new, then it is even harder to move the sprocket. Look.. Mount the engine, and hook everything up, and pull in the clutch, you will be able to pedal. Once you get 500 miles or so, you may be able to move the sprocket with your finger when you pull in the clutch. Maybe... Enjoy the ride..
