Narrative:
After 50% on start of left engine, the start valve light did not go out and the start switch did not go to automatic. I selected automatic and the start valve light went out and the pressure came up. I told the first officer not to fuel chop. I reasoned that the start valve was already closed and it could be fixed at destination. Later, I called maintenance to see if I had done something dangerous because it was against procedures. The technician on duty said that as long as the air was removed from the starter, no damage could have occurred. However, after thinking about it, I believe I should have fuel chopped the engine and selected automatic per procedures. I will fuel chop next time if it happens again. There is no reason for me to invent my own procedures.
