I surfured the MSD forums and found that the rotor tip is oriented at the bottom of the cap lugs. Theory is it is more efficient for the spark to jump across sharp corners than large flat areas. My cap lugs have the edges worn away at the bottom. I guess it is possible that the spark enegy is greater now that the sharp edges are worn creating the noise. So in theory as the cap wears it should continue to make the noise until it is constant or I could just get another cap, but what fun is that. I also have a hard time beleiving I am the only one the hears the noise, LOL!!!
