 My guess is that the static timing of the Pertronix 1 is not very accurate. I would trust what you are seeing with the timing light. In my experience, if the engine is in good shape, it will at least run over a wide range of timing settings. So it does not surprise me that yours is running at 30 deg BTDC. Whatever the cause, it is running, so I would go on from here, not start over.

What I would do at this point is make small adjustments to the distributor until you get the timing (according to the timing light method) to the 10 degrees BTDC you were aiming for. I recommend small adjustments because you will probably have to increase the idle speed adjustment on the carbs as you back off on the timing advance to keep the car running. Actually, it might be better to increase the idle speed first so you don't run into the frustration of the engine not running as you adjust the distributor.
