The reason you keep turning the shaft, as you have used rope is that you are working against the clutch and it slips. To remove the nut, insert a piece of SOFT material (I use a rod bearing from a car) between the large and small gears on the clutch side. This will bind the engine.There are no threads on any gear or the magnet. Use the PROPER tool in above reply.
