Confused about the timing on my '82 Prelude

I have, what I believe to be a non-California 1982 prelude. I?ve been wanting to do the timing. I believe that the non-Cal preludes correct timing is 12 degrees. However,

However, my timing marks show 16 degrees and what looks to be 2 degrees either side. I?m wondering if anyone out there has experience with these and can give me some advice.



Many thanks.

I assume this car has a carb and not EFI?

To check base timing you need to disconnect the vacuum advance.

But do I use the 16 degree mark?
