RPM Drop From Nuetral to Gear

I said it earlier. It changes rotor phasing. "When the spark fires" is triggered by the reluctor wheel. If the rotor is NOT aligned with a cap contact, the rotor is "out of phase." This causes a number of problems

1...The extra gap the spark has to jump causes a slight time delay which changes effective timing

2...Because the contacts are not aligned, "think further apart" the spark has to jump further, and the voltage goes up. At some point it can cross-fire to adjacent cylinders

3...This hot spark constantly jumping the gaps around the cap will eventually cause "tracking" in the cap, heat and ruin the cap material and turn it to carbon. Also, "more ozone" in there can't be good for things either

That's all I can think of for now, as if it ain't enough, LOL. As I said earlier, Google "rotor phasing"
