With the dampener at 15 (& that number is fairly close to dead on & is a better setting than any other amt no matter what else is going on) then with the magnet dead even with the reluctor tooth, that is the exact time/point that fire will jump from the rotor tip and at that point you want the rotor pointing fairly close to the underside of the #1 plug wire cap terminal. the springs will have the rotor retracted at that point when you are checking it with the cap off & the can will shift it CCW from that at rest position when running. the rotor tip and the cap terminal are pretty wide so you have alot of leeway there but that distance cannot be too great or it will misfire. this is "rotor phasing" which I dont think is the issue but yes we need to start at 15.
