Thanks gizmo , have already done the leed. Great video , I will try this tomorrow on the coil and I'll put in a new keyway just to make sure and that the key is in neat. I did notice after I put the flywheel on there was a tiniest bit of movement clockwise and anti but I asumed once I tightened the cup and nut up it wouldn't have any movement but now you have me wondering if something so small could actualy be the trouble. I wonder if the bottom part of the keyway sits /the cam that goes over the shaft has movement if so could this cause a problem ? Your know how is great and thanks again, rob.
