Hi.
Has anyone seen or measured the timing curve for a three cylinder twostroke standard ignition cdi system? E.g. yamaha or OMC, Ideally for the phealon system used by VolvoPenta 70 hp built only some years around 1978. Typically only some sort of static setting setting is documented but I would like to see how much it is retarted at high revs and also perhaps spot a overreving remidy.
