Another speculation (I'm not a
combustion engineer, and I don't play one on TV...) regards the
impulse couplings.
Having them fire at slightly different
times may increase the probability of the engine starting when the battery is
Low/on a cold day/when some fool is hand
propping.

C-85-12 Timing
I forget which mag fires the top plugs and which fires the
bottom, but the timing difference likely has to do with the way
the engineers want the combustion to proceed across
the combustion chamber from top to bottom or from
bottom to top.

Do any of you know what the reason is that the timing on a C-75- or
C-85-12 is set
RIGHT MAG --28 DEGREES BEFORE
TOP DEAD CENTER, AND the LEFT MAG -- 30
DEGREES BEFORE TOP DEAD CENTER ? ??
Just rebuilt my mags and I found these settings in the engine manuel.
Wondering WHY the difference in the right and the left mags.
Thanks
