Need help with rotor phasing

The other thing that "might" be......and there are various issues with this..........

is that the thing is "false" triggering for some reason..........either a problem electronically in the unit, or due to some EMI/ RFI problem

Don't you have "some other" ignition you can slap in there long enough to see if you can get a baseline?

Have you at this point actually checked the dist for proper phasing?

(Point that out if I missed it.........)
