Speed problem, 1978 c3

Hey guys,,,maybe one of you have had this prob,, I think common sense answers my question but,,,,say doing 60,,,it jumps 30-60,,,30-60,,,and occasionally it will settle down,,,odometer and tripometer seems to work properly,,,so would you say prob is in speedo head or?,,,thanks,,DR
