Tachometer adjustment?

Tachometer adjustment?
I was reading on the net somewhere that the fc stock
tach can be adjusted to get it close to a correct figure
when running the 20b, any one know what is needed to
adjust the tach?
I have opened it and looked in there,, I see 2 pots
that look like they could be adjusted but I am unsure
which is the one to mess with...
I could just start adjusting the thing but I thought I
would ask first..
matt
ps. reted,, i know you know the answer to the above
question, question is will you offer up this little bit if
help?

BTW, if you use this jury-rigged signal generator method, the 20B would read the signal at a 2700rpm calibration target, and the 13B would be 3600rpm.
Edit: I screwed up the 13B info, but I fixed it now. Sorry.

From the grave.
I was wondering how accurate this is setting it at the V-6 setting?
I did what was described in the grannySS link and my tach seems to be closer
to accurate but I don't think it's right on.

^ It shows you how on the grannyspeedshop link (see post #5). Just follow the steps for a V-6 conversion. I just want to know if the tach reading is accurate after doing this, or how do I check it?
With a timing gun like Ted suggested?
