Ron, anyone - I have labelled my 912ULS ignition switches A and B corresponding
to the ignition modules. I used separate toggle switches rather than the typical
keyswitch because I seem to recall that someone said the 912S starts better
on one particular magneto.
However, I now cant find a reference to that assertion. I do find that the Rotax
heavy maintenance manual says that the 912 timing is the same for both ignition
circuits (26 BTDC), but different on the 914 (A 26 BTDC, B 22 BTDC) so I am
beginning to think that I misremembered!
Any observations on the topic welcome.
in friendship
