I would suggest leaving the IF cans alone until you rule out all other faults, those are very delicate on the inside with hair thin wires, popping between stations sounds like some form of interference. Are there any electric fences in your area? Can you pick up the popping on any other radio? There is also a capacitor across the power line in these sets, if that's open you will get all kinds of noise.
