    This happens because the 2 cylinders which share the port are not equally spaced in terms of firing order. For example, the Leyland Mini with its 1-3-4-2 firing order has the 1 and 2 inlets siamesed and the 3 and 4 inlets siamesed. First the number 3 sucks the mixture out of the port, then there is less left for number 4.
