As long as the span of the rotor tip is in the range of the wire terminal when the points open, timing will be correct.
I will change my understanding of this if experts contradict the conclusion from their own experiences. (Hey, we're all here to learn  ) |
I'm still running the non-rev rotor with no timing change, and it's still fine. Based on that, you can swap back and forth.
However, the contact patch for the rev limiting vs. non-rev limiting rotors seem to barely, if at all, overlap. Is it possible that the PO had a rev-limiting rotor put in accidentally, they never adjusted the timing, and so when I put the correct one in, everything was perfect? Who knows...
Someone with more time, money and care than me should check this out! Good weekend project...
