Speedometer Adjustment for 5KTQ?

After comparing speedo with computer, 5 mph seems relatively consistant even
up to 60. I haven't had a chance to check higher speeds, but it seems the
deviation is closer to 5 MPH rather than 10% I originally thought. Yes it
has probably been doing this all along.
I dont know if I want to move the needle, as this would make the speedo
incorrect at low speeds, yes? Also, I'm afraid of breaking it or making it
worse than it was. I can live with 5mph deviation at 60. At least I know
how to correct for.
I wonder if the speedo reading inaccuracy correlates at all with the
odometer reading. I'll do some more sampling on a long trip.
I would be interested in any other information regarding correcting the
reading, particularly with changing the resistor.
Thanks for all replies.

Your speedo probably has always had this error. It seems that all 5kts of
this era had a 5 mph offset and a small slope error. I have a hard copy of
the original post for correcting the calibration and probably have a few
e-mail communications with the original poster in my files. I found that
moving the needle down by 5mph I got my speedo within 1 to 2 mph over the
range of 35 to 85 mph. Note that the scale doesn't start at zero but the
needle sets near the start of the scale. I haven't checked outside that
range. Changing the resistor will fine tune the upper end. I can dig
through my files at home if there is an interest.

Is there anyway to adjust the speed reading of the speedometer. Mine seems
to be reading a little fast after I replaced a gear(from spare unit) that
had caused the Odometer to stop working.
