Hi, fellow dodge enthusiasts, I have a 1923 dodge tourer and I need to replace the water pump because one of the gland nuts was over tightened and snapped the threaded part of pump off. If I remove the water pump do I have to retime the magneto to secure the ignition timing and if so before removing the discs between the pump and magneto do I have to index the coupling discs to enable reinstillation of the pump, advise greatly appreciated.
