Impulse magneto

After shutdown, I turn the prop until I hear the click, to leave the spring unloaded.
The harness had been replaced (professionally), engine run, no problem indications, easy start.
Yesterday there was no click.
Should I worry?

If you always used to hear the click and you no longer can without having changed the type of mag then something’s amiss.
Did this occur on the first flight after the harness replacement?

I always turn prop after final shutdown, until I hear the click. First time I haven’t heard it.
No flight yet – first run after replacement, just taxied back to our
hangar as too near night to fly. Engine is O-200 half-life engine.
I’ll check before start next time – maybe tomorrow.

Sounds suspicious, if it is a Bendix mag the oil slinger may have moved and jammed the bob weights.
