yes - its a mechanical part in carburettor cars, the centrifugal advance mechanism requires overhaul after some time as it siezes or becomes too sloppy (worn springs or worn weight pivots)
The ignitor and pulse generator can be checked with a fast sensing DMM. Its basic mechanic work. Everyone who repairs carb cars knows how to overhaul it.
In cuore the dissy had CB breaker points, which make it easier to overhaul.
