The belt may be just a bit too snug. Machines that turn with very little resistance in the mechanisms, especially recently cleaned and lubricated ones, tend to “free-wheel” when the clutch knob is released for bobbin winding simply from the belt tension applying a little extra side pull on the hand wheel.
If you have a good V-Belt on it, try loosening it off just a touch. If you have a rubber stretch belt on it, get a V-belt for it.
