That crank looks awfully far off center. It has to be a bit off center to work (meaning of eccentric). I would try to get it over the disc around the axle.
The actual amount is probably based on how much the valve moves in the cylinder and the geometry of the rods connecting them. Which side of the axle depends on whether the valve is inside- or outside-admission. (sorry, I don't know; might be able to look up). I think that both cranks should lead or trail the mounting pin.
