Re: rotor phasing
Rotor phasing is very important. When it is way off the spark within the cap can jump to the wrong post.prairiehotrodder wrote: ↑Mon Dec 06, 2021 11:48 am whats the point of this ? How do you correct it ? Can it be a problem ?

Moving the cap by re-indexing the locating notch or moving the rotor tip itself with an adjustable rotor is usually the way it is done.

Re: rotor phasing
Msd sells a adjustable rotor for making the adjustment to correct the spark phasing.

Re: rotor phasing
Has it been running a while?
Easy to see where its been arcing, edges of both rotor & terminal NG.
Not easy assuming those marks are from full mechanical & vacuum or where between.
Good luck.

Re: rotor phasing
You can also adjust the phasing by moving the at rest position of the mag pickup ring that is accuated by the Vacuum advance arm.
