Unless rotor phasing is so far out of whack that the spark jumps to the next post, no. It will have no effect. The rotor phasing and ignition timing are two separate things that are inter-related. The spark will occur at the same time in the cylinder regardless of phase. The exception to that is if phase is so far out that the spark doesn’t make it to the correct cylinder.
