I would be inclined to carefully inspect the shielding of the wiring related to that. The HT leads and plugs also need careful inspection of course. A loose cap, a corroded lead etc may cause a spark to occur where it shouldn't and so generate a tick. 2) Can you tell if you hear one tick per revolution of one tick per four revolutions? That would tell you whether you are looking for a primary side, or an HT/plug related issue 3) Are your 'P' leads long enough to swap from side to side? Doing so would again isolate the issue to the starter system and wiring, or the magneto. I suspect you are going to have to narrow things down by swapping/replacing/inspecting.
