[urq] Ideas for rough running continued - Solved!

[Ed Kellock]

Hmmm, well, the tach drops as quickly as it mechanically can.
It's clear that there is no spark firing at the plugs.
When it ignition cutout ends, there is often a backfire out the
tailpipe.
If I'm driving when the cutout occurs, my body lurches toward the
steering wheel.
I actuated the throttle while holding the idle switch in the closed
throttle position and the cutout still occurred.

Maybe I don't understand your question.
Haven't had any doubt that the ignition is dead when this occurs.
It occurs while driving as well as sitting idling.

The ignition switch was replaced a year or two ago for another reason.
It did not correct that other situation.
