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

There should be timing marks on the prop flange. They'll be
on the bottom when the #1 cylinder is at TDC, and you line them up
with the crankcase seam. Shouldn't need the other timing doodad, which
isn't all that accurate.
