The springs don't regulate how much timing you get, they regulate at what RPM the timing advances. You need to use smaller pins or longer slots in the mechanical advance to get more timing. The vaccum advance should only come in in high vaccum situations such as cruising on the highway, usually to give you better gas mileage.
