Thanks John but I was aware of the potential problems before you took the
time out to chew on me. Since you're wrong about "wringing my hands and
begging for an okay", I don't consider your being an A&P any help at this
time...

However since most specs have a range of values, I am looking for that
range.

yes there are timing marks. Unfortunately I can't access the case seam
due to nosebowl and air plenum sheetmetal that I'd prefer not removing.

So I guess my question still remains on difference between 30/32 and
28/30...

Thanks anyway, Dick

The correct answer as to why we like to maintain correct magneto timing in
aviation is to prevent catastrophic engine failure such as loss of
cylinders, holes burned through pistons, thrown rods and other negative
consequences of detonation. Is this answer clear enough for you? Does it
help that I'm an A&P? Why would you even bother to check the timing if
you weren't going to do anything about it except wring your hands and beg
other people to tell you it's OK? Do you go through the same agony when
your oil's low, or your tire pressure's low? I can't believe that in the
two days you've spent waffling over this, you couldn't find the time to
loosen 4 nuts, rotate 2 mags, torque 4 nuts and make a logbook entry.

I think it will be quiet around here now. So long.
