Timing light for multiple spark Ignition??

The thing with timing lights reading incorrectly with multi spark ignitions is....... you often have no clue they aren’t reading right.
Sometimes the strobe is inconsistent and jumping around, so you know it’s not reading correctly.
But I can tell you from personal experience........ sometimes everything appears to be working normally....... when in fact it’s not...... at all.

I only trust lights with no dial-back type features.
