Speedometer Problem

I recently took the dashboard out of my 2006 Cobalt LT, in an attempt to find the source of a soaking wet passenger front floor (see my post in the appropriate section). While the instrument cluster was out, I wanted to look into possibly changing the color of my dash lights. I accidentally moved the speedometer needle, and it was reading about 12-14 MPH slower than you were actually traveling. I saw a post here about resetting the speedometer by cycling the ignition on and off, manually placing the needle to zero, and then cycling the ignition again. Now, the speedometer doesn't drop below 35. Is there some step I am missing?

Move the needle counter clockwise until you feel the stop. Then move the needle manually counterclockwise to the approximate 35 mph degrees. Do this with no power to the cluster. Then fire it up again and see how off you are and repeat as needed.

By experience on these needle should be 2 needle thickness below the zero mark. But they are all slightly different.
