      There is a placard on my 1974 Traveler that says I should start only on the left mag. Why is that? I’ve started it on both and it seems to start fine.

      Only the left mag is impulse coupled and retard the spark at low rpm so as not to kick back on the engine. A right mag fires at 25 BTDC always.
