Alright. Do we all agree that the rotor is locked to the reluctor? YES Is the pick up "fixed" in place with no vacuum advance? YES Then what you really need to accept(like me) that it will always trigger in the same position.
The rotor Is locked to the reluctor/trigger. YES But its relationship to its pickup Does Change with the mechanical advance.
The pickup is Fixed on a plate, But that [plate Is moved by the Vacuum advance. So No on that second statement. That plate with the pickup is indeed moved in relationship to the reluctor.
Lights are being turned on at different timing events for sure, as we see.
Further Robert made a mistake with his numbers. Hes stacking the mechanical advance with the vacuum advance to show the Rotor rotates that combined amount of degrees away from the caps pickup terminal. This says, hes missing it.
That's incorrect the Rotor and reluctor only rotates away from the cap terminal and the pickup by the Mechanical rotational advance. Witch would be 10 degrees at the cap or 20 degrees at the crank on a 20 degree mechanical advance distributer. The Vacuum advance only moves the pickup plate in the opposate direction of the rotors movement not Effecting the rotors position to the cap but indeed Further effecting the relationship between the pickup and the reluctor
Previous posts and even my quote here take the vacuum advance out of the equation by disabling it. So lets change your answer to YES. We all agree that the vacuum advance will change rotor phasing. Please explain how the rotor can be in a different position if the rotor is locked to the reluctor, and the trigger happens when that reluctor passes a fixed place pickup.
