I have no idea about MSD distributor. If it is variable reluctance, then what I said could be possible. If it is optical, then that is different, no way what i said, could be true. So it would be something else, and no idea what.
Yes the MSD pro billet is a magnetic distributor. But I just couldn’t see the pick up coil and the reluctor clearly. So now I tried to stock distributor it is easy to see I set it up at 13° nothing happened I checked first bar it wasn’t triggering the MSD box so I pull it out and spin it by hand And it throws fire like hell I put it back in and it doesn’t just more weird stuff with this motor I’m getting really tired of it
