I would suggest you use the leftover as a base in the grill and not as the fresh in the chimney.
I completely agree. When I try to relight used charcoal in the chimney it doesn't seem to want to light. I think it is because the pieces are smaller and they fit more compactly in the chimney, making it obstruct airflow.
I always light new charcoal in the chimney and pour the lit charcoal on top of the remaining used charcoal in the grill. I then let the grill preheat as the used charcoal lights. You don't need to light as much new charcoal either as the used charcoal will light.
