Please check the readings that you report above again.
You should not be able to go from 5* ATDC to 45* BTDC. That is 50* of change. Something is not right. Maybe you misread something or wrote it down wrong.

Yep.
At first he had 20º to 25º advance. After adjusting points and timing he now has 50º. It doesn't compute.
