Default Round speedometer recalibrating

One of my "A's" with a round speedometer works fine but reads 45 when I'm only going approximately 35 mph. Is there some way to recalibrate rather than send it off and get it rebuilt?

Have you checked the odometer for accuracy on a measured mile ?If it is accurate the problem would be in the speedometer. If it is also reading high,(more than a mile),you may look into installing a larger speedometer drive gear to slow it down.

Do you have the correct size tires/wheels on it? That will also throw it off. Good Luck

I've got the right size tires and wheels but I haven't checked the odometer. I'll do that.
