Depends on your definition of perfect.
The way a whiscome works with a gear rack on each side of the gear will create a slight twisting moment around the vertical axis (i.e twist left or right as you are holding it). Due to the centre of gravity of each piston being offset to one side of the cylinder axis.

Is it noticeable? Probably not
Is it 'perfect'? No
