Timing is not set at TDC. Set it at the advance mark. Points should open when the mechanical advance is held in the advance position, not the retarded position.
If you’re trying to set the retarded position at TDC, that method is very flawed. With that method, you’re assuming the mechanical advance unit is precisely 25 degrees of travel—-they aren’t.
